The precondition of constructing single-stage highpowerfactorhighpower supply based on flyback topology is that the release rule of transformer energy-storage is clear.
构造基于反激拓扑的单级高功率因数的大功率电源的前提是弄清变压器的储能和释放规律。

In the no-load test of transformer, because of the low powerfactor and non-sinusoid current waveform, the high precision measurement is difficult.
