The output swing can be improved efficiently with push-pull class-AB output stage, thus high-drive capability with low power supply is obtained.
输出级采用推挽式AB类结构，能有效地提高输出电压的摆幅，从而得到电路在低电源电压下的高驱动能力。

The first stage is pushpull forward converter, and the second stage is a dual buck inverter(DBI).
该静止变流器前级采用推挽正激式变换器，后级采用双降压式逆变器。

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.
