本发明属于电源测试技术领域，尤其涉及一种多相开关电源效率调试装置、方法及系统。The invention belongs to the technical field of power supply testing, and in particular relates to a multi-phase switching power supply efficiency debugging device, method and system.
背景技术Background technique
随着集成电路超大规模的发展趋势，芯片的功率密度越来越高，功耗的增加要求板级电源能够提供更大的电流输出。对于大于25A的直流降压开关电源，单相开关电源的效率下降、散热困难等都将制约其性能。多相电源可以使MOSFET和电感的电流成倍数降低，并且可以减少印制电路板或者器件上的热点，此外多相电源还具有纹波电压低、所需电感体积小的特点。With the development trend of ultra-large-scale integrated circuits, the power density of chips is getting higher and higher, and the increase in power consumption requires board-level power supplies to provide greater current output. For a DC step-down switching power supply greater than 25A, the efficiency of the single-phase switching power supply and the difficulty in heat dissipation will restrict its performance. The multi-phase power supply can reduce the current of MOSFETs and inductors by multiples, and can reduce the hot spots on the printed circuit board or devices. In addition, the multi-phase power supply also has the characteristics of low ripple voltage and small required inductor volume.
为了让多相电源始终工作在一个较高效率的情况下，需要在低电流时开启较少的相，电流较大时较多的相同时工作。一般多相开关电源的效率最大值在负载电流50-60％左右时。因此，寻找多相开关电源增加相或者减少相的临界点，对于提高多相开关电源的效率就显得至关重要。In order for the multi-phase power supply to always work at a higher efficiency, it is necessary to turn on fewer phases when the current is low, and more phases to work when the current is high. Generally, the maximum efficiency of multi-phase switching power supply is around 50-60% of the load current. Therefore, it is very important to find the critical point of increasing or decreasing the phase of the multi-phase switching power supply for improving the efficiency of the multi-phase switching power supply.
目前，对于加减相的临界点的查找一般采用手动测试方式实现，但是传统的手动测试方法操作繁杂，而且由于效率测试的参数记录多、耗时长，测试时间变长导致器件温度上升，影响测试条件，最终得到的效率曲线不平滑，同时，手动测试人为误差较大。At present, the search for the critical point of the addition and subtraction phase is generally implemented by manual testing, but the traditional manual testing method is complicated to operate, and because the efficiency test has many parameter records and takes a long time, the longer test time will cause the temperature of the device to rise and affect the test. conditions, the resulting efficiency curve is not smooth, and at the same time, manual testing has large human errors.
