The voltagestress of each main switch is only half of the input voltage.
其主开关管的电压应力均为输入电压的一半。

ZVS is achieved for each main switch without any auxiliary circuit. Voltagestress of each main switch is a half of input voltage.
每个主开关电压应力是输入电压的一半,并且全范围实现ZVS而不用附加任何电路。

So it is usually needed to connect several diodes in series to endure high voltagestress, but design of balancing voltage of these diodes is difficult.
