LLC converter (Half Bridge, Diode Rectification)


This topology can achieve ZVS (primary side switch) and ZCS operation (secondary side switch) simultaneously. It realizes low noise and high efficiency by generating a sinusoidal current waveform with the switch network and resonant circuit.
This circuit consists of a half-bridge switch circuit on the primary side and a diode bridge on the secondary side, it is used for relatively lower power (500W or less)
