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。

Push-pull circuit topology is used for the main circuit, together with simple drive and dual-direction reset of transformer flux.
主电路采用推挽电路拓扑，驱动简单，变压器磁通可以双向复位；

The main disadvantage of push-pull class A amplification over single-ended class A, is the necessity for a phase splitter stage to generate the oppositely-phased drive signals.
