With the development of switching power supplies, soft switching technology has been widely developed and applied, and many high-efficiency circuit topologies have been studied, mainly PFM-type soft switching topologies and PWM-type soft switching topologies. In recent years, with the widespread application of third-generation semiconductor devices GAN and the continuous development of PD power supplies, this has provided another opportunity for the development of power converters. For half-bridge converters, if properly designed, soft switching conversion can be achieved, so that the switching power supply has higher efficiency and greatly reduces the size of the power supply.
