New series resonant converter for variable reluctance motor drive

A resonant-type converter for a variable-reluctance motor drive is proposed to perform zero current switching of all solid state devices. The resonant circuit is partially resonant rather than fully resonant from the viewpoint of the capacitor. The power circuit of the converter can be realized with unidirectional naturally commutated switches. The converter has many advantages, such as low voltage stress or improved voltage utilization, low loss, and no stress in the switching instant. The operating principle and current regulation method are introduced and verified through simulation
