Abstract

A recent innovation in current source inverter (CSI) drives has been introduction of pulsewidth modulation (PWM) for the purpose of improving the quality of the load currents and voltages. However, the typical six-switch CSI circuit is not compatible with all standard PWM techniques, thus limiting the number of schemes that can be used. The modified CSI circuit discussed removes most of the restrictions at the cost of an extra switch. Additional advantages include faster response times through modulation index control and higher efficiency. A detailed steady-state analysis and design procedure is included. The feasibility and performance of the modified CSI are verified by simulation and experimental implementation on a 5 kVA converter
