* Matrix converter is a direct AC-AC power conversion device. Compared with the conventional AC-DC-AC PWM converters, matrix converter has some obvious advantages, such as simple and compact power circuit. It has lower cost and weight, enhanced power density, extended life time and enhanced reliability. Matrix converter could provide sinusoidal input/output currents and adjustable input power factor. It can implement real four quadrant operation and has regeneration capability. * Matrix converter is a direct AC-AC power conversion device.
