A novel LCL resonant converter with PWM control-analysis, simulation, and implementation

A novel three element resonant converter capable of driving voltage type load with load independent operation is analysed using the state-space approach. Pulse width modulation is employed to control and regulate the output voltage. Closed form solutions are obtained under steady state conditions. The experimental study of a prototype converter reveals complete agreement with the analytical and SPICE simulation results. Typical experimental oscillograms are given to verify the basic principles.<
