Sinusoidal Voltage Output Inverter for Motor Drives Using Discontinuous Current Mode Operation

Abstract

This paper proposes to apply discontinuous current mode (DCM) for motor drive inverters to avoid the problems caused by high dv/dt in output, with relatively small filter components. A three-phase configuration for the DCM operation is proposed and a direct current control method and its application to PMSG drive are discussed. The experimental demonstration with a 2-kW PMSM are shown.
