摘　　要：提出了一种关于开关电源在特殊工作模式-非静态负载下输出端功耗的计算方法。当开关电源输出端出现非静态工作模式时,对于传统的功耗计算方法会经常出现效率大于100%的情况,而实现在非静态负载情况下计算出比较符合理论与实时的功耗真实值,特推出此计算验证方案,供后续出现开关电源输出端非静态工作模式下的功耗计算参考。A new method for the calculation of the power consumption of the output side of the switching power supply under the special working mode-non-static load is proposed.When the output of switch power supply appears non-static working mode,the traditional power consumption calculation method often appears the efficiency more than 100%.However,the real power consumption value which is more consistent with the theory and real-time is calculated under the non-static load.This calculation verification scheme is presented for reference for the power consumption calculation in the non-static working mode of the output end of the switch power supply.
