The difference between a hard switching and quasi resonant flyback converter is the turn on time point of the primary switch.
硬开关和准谐振反激变换器之间的差异在于一次侧开关的开启时间点。

The flyback converter running in discontinuous conduction mode can be operated in hard switching or quasi resonant (or valley switching, or ZVS) mode regarding the primary side switch.
电感电流断续工作的反激式变换器一次侧开关可工作于硬开关或准谐振(或谷值开关或零电压开关)模式。
