Abstract

A pulse width modulated (PWM) rectifier/inverter system using insulated gate bipolar transistors (IGBT's), capable of switching at $20 kH_z$ is reported. The base drive circuit for the IGBT, incorporating short-circuit protection, is presented. The inverter uses an Undeland snubber together with a simple energy recovery circuit, which ensures reliable and efficient operation even for $20 kH_z$ switching. The front end for the system is a regenerative single phase full bridge IGBT inverter along with an AC reactor. Steady-state design considerations are explained, and control techniques for unity power factor operation and fast current control of the front end power converter, in a rotating as well as a stationary reference frame, are discussed and compared. Results from computer simulations and experimental results for a 1.5-kW prototype system using GE IGBT's Type 6E20 are presented.
