Description of invention: ^ [Technical field of invention] f A method and circuit for starting timing control, in particular, a method and an implementation circuit for determining whether a working voltage is normal and controlling a starting timing. [Prior Art] Nowadays, the general power supply includes a power factor correction (PFC), a pulse wave control unit or a conventional power control unit. In order to save space and save power, the above unit All of them can be integrated into a different integrated circuit (1C, integrated circuit) or integrated into the same integrated circuit, integrated into the function of detecting the input voltage and self-starting, the integrated circuit borrows Controlling and determining whether the input AC power reaches the operating voltage and controlling one of the integrated circuit bias voltages (Vcc), 疋疋=turning on the circuit unit in the integrated circuit, when the input AC power is not up to normal The working voltage can be automatically turned off and repeated to detect whether the AC power reaches the normal working voltage range. The above-mentioned customary creation can be found in the "Modified Switching Power Supply" of the Republic of China Patent Notice No. 5,183 No., please refer to In the second and third figures of the conventional creation, it can be seen from the above figure that the waveform 3 in the second figure is the voltage waveform of the node 第二 of the second figure. It is known that the step of measuring the alternating current power and starting the integrated circuit is that the bias power Vcc is first charged to the capacitor C1 to make the voltage of the node χ start (start_up) f pressure, then the units of the circuit are activated, if If the flow power does not reach the normal working voltage, the load effect of the integrated circuit start-up will cause the voltage of the node to fall (Off), and the value of each phase of the paving circuit is turned off, and then the charging voltage is raised to the starting voltage value. And repeat the above process until the AC power reaches the normal working voltage. Although the above-mentioned operation mode can predict the timing of the AC power, the time when the AC power reaches the normal working voltage cannot be expected, resulting in the start of the integrated circuit and the AC power. The timing of the hang = input is different. 'The difference in timing may cause the booting time to be too short. There will be an impulse I, and the component will be damaged. ': 3⁄4. When the operation suddenly occurs, the overload will cause the 2 X voltage to drop. After the () voltage value is followed by the compensation circuit, and the integrated circuit is turned off, the load effect of the integrated circuit disappears and the AC power remains normal. M ' causes the voltage of node x to rise again to the starting voltage value, and then falls due to overload; the product circuit will be quickly turned on and off during the period of initial measurement of the parental power and overload 5 200847594 Jobs are quite shredded and overheated, more direct injury and the need for improved control methods and circuits.

The bias power is transferred to the shop value. When the AC voltage has reached the operating voltage of the 3 wipes, the bias power is increased to the start value to cause the integrated circuit to start. In the circuit (4), when the bias voltage is reduced from the start-up value to the cut-off voltage value, the integrated circuit is turned off and the bias power is continuously decreased to the standby voltage=, and Standby The rising start value of the Xia, so it depends on the excess, and the method of the method is the same as the method of the first step. The first step of the above method is to first determine the working voltage value of the towel and the standby voltage value 71. And then obtaining the input power parity value 72 and determining whether the average value of the input power is greater than or equal to the normal working voltage value 73, and if the normal operating voltage value is not greater than or equal to the value, the input power average 72 is continuously obtained. If the bias power is greater than or equal to the power-on-record, the integrated body is greater than or equal to the positive fjl. Circuit 76; please refer to FIG. 2, which shows the step of overload protection. When the integrated circuit continues to work 81, it is judged whether the circuit system is overloaded. If overloaded, the second judgment = whether the bias power is less than or equal to The off-voltage value 83, if the bias (four) force is less than or at the cut-off voltage value, causes the bias power to continue to fall, and begins to determine whether the bias power is at a voltage of 85, when the bias power is less than or equal to the standby voltage value After 86 'At the same time, it is judged whether the bias power is greater than or equal to the starting electric power, and the dust power is greater than the scale of the starting voltage value, and then the circuit is decorated, so that the method can ensure the deviation. The power is only increased after the input AC power is turned on, so it can ensure that the money power reaches the normal working power system and has sufficient buffer time between the two to reach the starting voltage value. When the value is reached, the bias power can be forced to continue to decrease (4)...if voltage value, to avoid the integrated circuit quickly repeating the opening and closing and accumulating (4) her until the residual state is released and resume normal operation.

The average value Vav of the input power is the Guanda normal working voltage value, and the input power of the buffer unit 2〇Vav t can be input to the power factor correction (4) unit η as a reference for the correction factor The bias input terminal obtains the bias power I, and the bias input terminal is connected to the biasing unit 23 and the bypass adjusting unit 24, the bypassing the control unit 22, the control unit 22 _ input power average When the value Vav or the bias voltage is abnormal, the bypass unit 24 is instructed to divide the bias power Vee, so that the voltage input to the bias side unit 23 is maintained at the standby voltage value, #the input power average value - or The bias power Vee positively controls the fresh element η to stop the partial voltage, so that the bias power VcM is raised to the normal operating voltage value, and the control unit 22 generates the startup signal Vbk. Let the integrated circuit W start to work; if the integrated power supply is auxiliary, the guiding power biasing unit swells the power i to the cutoff voltage value, and the control unit 22 makes the side The circuit adjusting unit 24 starts to divide the voltage so that the bias power Vcc is maintained at the voltage value and then rises to the value of the boost, so that the clock is turned on and off until the overload state is released; therefore, the start timing control circuit 2 can determine the AC power Vac. Whether it has reached the working voltage of the crane and judged the bias The power has reached a sufficient voltage to the integrated circuit starts normal BU may further ensure that the integrated circuit! The start-up and the input power average-stable have a sufficient buffer time to prevent the excessive surge current from damaging the circuit components, and the overload voltage Vee drops to the standby value and then rises to the start-up.
