Abstract :
The use of resonant converter principle in variable-speed ac drives is presented. A control strategy to obtain high-frequency quasi sinusoidal dc link waveform permitting zero voltage switching is proposed. This operation results in reduction of commutation stress and switching losses in the power devices. Operation of a current-controlled three-phase resonant dc link converter is studied. Simulation and experimental results are given.
