LLC converter (Half Bridge, Diode Rectification)
Description
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)
