Current rectifying and wave filtering circuit 622 connects power input 621, to be rectified and be filtered alternating current.InputEnd is come in from the both ends "+48V, GNG " through resistance R1 if it is D/C voltage, and the effect of this resistance is current limliting, if subsequent routeWhen there is short circuit, the electric current that resistance R1 flows through just be will increase, and both ends pressure drop and then increases therewith, will be from dynamic circuit breaker when more than 1WOpen, resistance value increases to infinitely great, protects input circuit+48V not by the influence loaded to reach) enter rectifier bridge after current limlitingD, resistance R1 and varistor RV constitute a simple overvoltage crowbar, and RV is a pressure cell, are non-using havingLinear semi-conducting material manufacturing forms, and C-V characteristic is similar with zener diode, and normal condition shows high impedance status,The electric current flowed through is seldom, when voltage height to it is certain when (be primarily referred to as high impulse string when peak surge such as thunders to pass throughAlternating current seals in into), pressure-sensitive RV can show short-circuit condition, directly the entire input total current of interception, and subsequent circuit is made to stop workMake, at this point, since all electric currents will flow through R1 and RV, because R1 only has the power of 1W, so moment can open a way, to protectEntire circuit is not damaged.
When exchanging AC input, then bridge rectifier be rectified using the one-way conduction of diode it is most commonAlternating current is changed into direct current by circuit.When direct current DC(+48V) voltage is directly entered rectifier bridge DBD, in output one justNegative DC voltage down, if+48V power supply itself is also direct current, the effect of that rectifier bridge D is exactly that play to input is poleProperty protective effect, no matter input it is upper just lower negative or it is upper it is negative under just will not all damage driving power, by C1 C2 L1 carry outFiltering, this is a LC Π type filter circuit, it is therefore an objective to by the smooth direct current of the voltage waveform after rectification.
It clamps absorbing circuit 623 to connect on transforming circuit 624, carries out voltage to the output to current rectifying and wave filtering circuit 622Limitation, absorbs the too high voltages on transforming circuit 624.
Pincers road circuit there are the reasons why be in fact exactly the metal-oxide-semiconductor protected inside IC chip, after process is rectifying and wave-filteringVoltage be divided into 2 tunnels, all the way by after transformer winding into the TK5401 of IC chip U1 the 7th, 8 feet, this road be by R1,Then C3, D2 are also connected to 7,8 feet, this R1, C3, D2 just constitute a simple clamp circuit, major function be exactly forAbsorb spike and surge and the effect of RV varistor unlike, RV mainly prevents from thundering or guarantor is played in city's surgeShield effect, clamp function are the inverse electromotive forces for absorbing transformer TRANS2-2 winding both ends, eliminate self-oscillation, play quicklyReset response is prepared for transformer a cycle, if transformer, which cannot reset, to be saturated, can lose induction reactance, R1 andC3 constitutes a RC charging and discharging circuit, and for the electromotive force reversely accumulated, D2 is mainly buffer action, and transformer is in positive half cycleWhen, induced electromotive force be it is upper just under it is negative when, make to have suffered loop and be in an off state, and when transformer enters negative half period, give pincersPosition circuit provides access, is quickly in an off state electromotive force loop, and when isallobaric device enters negative half period, give clamp circuitAccess is provided, quickly discharges electromotive force, protects the metal-oxide-semiconductor inside IC not punctured by spike and damage to reach.
The working principle of chip U1: this IC--TK5401 driver, main feature are for without on application circuitIt is designed using electrolytic capacitor.The IC's is mainly characterized by high-low voltage overcurrent protection compensation, does not need electrolytic capacitorHigh PF value.650/1.9 ohm of built-in high voltage power metal-oxide-semiconductor supports general AC input voltage AC85V--265V, the IC'sDriving circuit 62 is by pulse detection leakage current peak value, in D/ST(7 foot, 8 feet) hold voltage to close power when being higher than OCP voltageMetal-oxide-semiconductor, residual current protection are connected to s/ocp(1 foot) and GND(3 foot) between current sampling resistor.When the pressure drop of sampling resistor reachesTo OCP threshold voltage, it is shut off power MSG pipe.
The transformer of more popular theory, the circuit uses inverse-excitation type working method, the i.e. phase of the primary and secondary of transformerPosition be it is opposite, in the same time, the two correlation 180 degree.
The foundation of transformation for the first time: when U1 is powered on, the internal activation circuitry being connected to by 7,8 feet is opened to power supply using U1Beginning work, U1 is also " pole G " that output square-wave pulse passes to metal-oxide-semiconductor inside U1 to grid at this time, connects the pole D with the pole S,At this moment the pole D and S grades of equipotentials, and the pole S is ground connection, equal to one end instant earthing transformer, to generate circuit, is becomeDepressor is inductive element, and electric current cannot be mutated, so own can generate induction reactance to prevent current break.According to linear curveIt is changed, slowly rises, it can generate an induced voltage gesture opposite with it to inhibit suddenly in order to prevent itIt, so, winding and time group winding below will and then generate electromotive force, to generate voltage, electricity-magnetic-electricity turnsThe mechanism changed lies also in this, this is the characteristic that transformer and magnetic material itself have certainly.
The foundation of second of transformation: (we usually cry it just after the winding generation electromotive force below transformerFeedback power supply winding), it is rectified by D3, R3 current limliting, then be divided into two tunnels after C4 is filtered and be powered, gives the 2nd foot of U1 all the wayPower supply, another way are powered to photoelectric coupled device PC817, the entire PWM power supply control when the 2nd foot starts power supply, inside U1System will automatically go to by positive feedback winding power, and internal oscillator circuit is made to work on, thus the 2nd pulse control letter of outputBreath opens metal-oxide-semiconductor secondary open-minded, and use MOS so in cycles constantly handles open and closed and then transformer is allowed to workIn electricity-magnetic-electricity transition status.
Figure 10 is chip TK5401 working sequence.Vbridge is 1 foot voltage of chip, and Vcc is 2 foot voltage of chip, and V and I areThe voltage and current of 7 foot of chip.
Each pin function of U1,8 feet are MOS input terminal, and 6 feet are sky feet, and the external capacitor of 5 feet is oscillating capacitance, directlyIt connects and determines RC time constant, be exactly the charge and discharge time, the general metal-oxide-semiconductor that charges is to turn on the time, and electric discharge is turn-off time, 4 feetIt is voltage detecting foot, by the duty ratio of the voltage value control output pulse to 4 feet, 3 foot ground terminals, 2 feet are U1 power supply feet, theThe capacitor of the external resistance of 1 foot and the 5th foot constitutes RC circuit, and to oscillation source is provided inside U1, the charge and discharge time of pulse is normalDirectly determined by this resistance and capacitor.4 feet external optocoupler PC817, other end PC817 and the both ends output circuit R4 phase are simultaneouslyConnection, R7 are to play the role of detecting electric current herein, and according to voltage=electric current * resistance principle, electric current is bigger, the electricity at the both ends R4Pressure will be bigger, and voltage is bigger, then and be connected to the PC817 at the both ends R4 and also have voltage and begin to turn on, secondary side after conductingRV also can and then be connected, be exactly its internal resistance decline, so the voltage of the 4th foot will rise, rise after with U1 the insideBasic voltage compare, then can directly export a signal make metal-oxide-semiconductor deduction shutdown, to reach constant current purpose.
Constant-current circuit 625 connects transforming circuit 624, carries out constant current output to control transforming circuit 624.Rectification output electricityRoad 626 connects transforming circuit 624, exports to carry out rectification again to constant current output.It is purple that rectifying output circuit 626 connects LEDOuter lamp 61.
After transformer work, secondary will export a voltage and be rectified by D4, and C8 and L1 are filtered, then giveLED light is powered, and L1 here is in addition to that can filter, and there are also the effects of afterflow, is just to maintain the consistency of output electric current, justBeing cannot this unexpected characteristic using the electric current in inductance.
Using driving circuit 62 and LED ultraviolet lamp 61, more embodiment ideas of energy-saving, since 61 power consumption of LED ultraviolet lamp is lower,Bactericidal effect is good, and is driven using constant current, exports stable electric current to drive LED ultraviolet lamp 61 to work, improves bactericidal effectWith the service life of LED ultraviolet lamp 61.
Potentiometer RP is also parallel on LED ultraviolet lamp 61.By itself resistance value for adjusting potentiometer RP, thus it is possible to vary in parallelThe shunting size of circuit, so as to the sterilization dynamics appropriate adjusted to LED ultraviolet lamp 61.Flow through the electricity of LED ultraviolet lamp 61Stream is bigger, then 61 intensity of illumination of LED ultraviolet lamp is bigger, then bactericidal effect improves.This process is limited in effective sterilization intensityAdjustable range in.
The 11st capacitor C11 is parallel on the anode and cathode of power supply unit 741.This 11st capacitor C11 can improve electricityThe stability of the output of source portion 741 electric current.Indicator light 742 uses LED lamp bead.LED lamp bead has lower power consumption.Power supply unit 741To connect external power supply, the second transformer T2's is another for side including the second transformer T2 and rectifier bridge D, the second transformer T2Side is to connect rectifier bridge D.It can be applicable in external different supply voltage, be depressured, passed through by the second transformer T2Rectifier bridge D converts alternating current to direct current and is powered for late-class circuit.
