Abstract
A T-type inductor-capacitor-inductor (LCL) resonant converter and its soft switching modulation method under a full power range. A full bridge inverter circuit is provided at a primary side of a T-type inductor-capacitor-inductor (LCL) resonant converter. The full bridge inverter circuit includes four metal-oxide-semiconductor (MOS) transistors. A half bridge rectifier circuit is provided at a secondary side of the T-type LCL resonant converter, and the half bridge rectifier circuit includes two MOS transistors and two equalizing capacitors. The soft switching modulation method for the T-type LCL resonant converter under a full power range is provided based on the T-type LCL resonant converter. The soft switching modulation method requires all switching transistors to operate at a duty cycle of 50% within one cycle. A high-frequency alternating voltage of the primary side has a symmetrical waveform, and a high-frequency alternating voltage of the secondary side has a square waveform.
