对移相控制零电压开关PWM全桥直流变换器的新型理论分析方法

The new theoretical analysis method for the phase-shifted zero-voltage-switching DC/DC PWM full-bridge converter

对移相控制零电压开关PWM全桥直流变换器提出了一种新型的理论分析方法,该方法在传统分析方法的基础上,采取将变压器副边整流二极管等效为一个理想二极管和一个理想电容器并联来展开讨论,从而使理论分析波形更好地吻合于实验波形。

This paper proposes a new analysis method for the phase-shifted zero-voltage-switching DC/DC PWM full-bridge converter. Compared to the traditional analysis method, the new one make full discussion on the converter: The output rectifier diode is equivalent to an ideal diode parallelling with an ideal capacitance. This makes the theoretical waves be approximate to the experimental ones.
