传统的推挽变换器存在着一些固有的缺点,诸如开关管的电压应力高、难以实现软开关等,限制了它的应用范围。
There are some intrinsic drawbacks in traditional push-pull converter, such as higher voltage stress and hard-switching of the switches, so the application area of the converter is limited.
在输出级设计时,为了提高效率,采用了推挽共源级放大器作为输出级,输出电压摆幅基本上达到了轨至轨;
When designing output stage, in order to enhance the efficiency, it uses the push-pull common source stage amplifier as the output stage, the output voltage swing basically reached rail-to-rail.
最后,本文还提出了另外几种零电压零电流开关PWM推挽三电平直流变换器。
Several zero voltage and zero current switching PWM push pull three level converters are proposed.
