    Abstract: In motor control of electric vehicles, a snubblerless 10 KVA Matrix Converter uses discrete 65 Amp, 1200 Volt MOS Controlled Tyhristors (MCTs) to minimise commutation time and so achieve the optimum waveform quality, particularly useful when controlling induction motors in applications where the controller may demand very low output voltages. The matrix converter has significant advantages over the conventional dc link converter by eliminating the dc link capacitor.

    Abstract: An AC to DC converter comprises a bi-directional switch array converter which converts a three phase AC supply at 50/60 Hz to a high frequency single phase drive for a series resonant parallel loaded tank. The tank is transformer coupled to a rectifier and filter to give a high voltage isolated DC supply to drive a load. The switching of the converter is based on control of the resonant tank to operate as close to a desired tank reference voltage as possible.
