A GRID-TIE MATRIX RECTIFIER IN A MULTIPLE INVERTER-MOTOR DRIVES

Abstract

This paper mentions the grid-tie rectifier structures in multiple inverter-motor drives. The bidirectional matrix rectifier topology  using bidirectional switches with many advantages is analyzed in detail. A specific PWM method is adopted for the matrix rectifier to achieve  the highest performance of the proposed structure  such as a sinusoidal input waveform, unity power factor at the line frequency, bidirectional power flow ability. The simulation results verified the advantages of proposed matrix converter topology with PWM modulation method.
