摘要
分析了 PWM 开关型变换器中,变压器直流偏磁问题产生的原因。给出了一种解决直流偏磁较为实用的拓扑电路,并分析了它的工作原理。该电路的有效性在20 kHz/2 kW 的全桥逆变电源中得到了验证。
By analyzing the causes of the magnetic bias in the PWM converter,a new approach was given and its working principle is analyzed.The effectiveness of the circuit is proved in the 20 kHz/2 kW full bridge inverter.
