Abstract :
The authors propose an improved version of the known pulse width modulation (PWM) controller topologies that can become a practical alternative to line-commutated AC controllers. The improvements include the use of typical unilateral switches, typical gating patterns, and reliability enhancing by-pass capacitors. The authors also present the analysis and design of the proposed converter topology, with key theoretical results verified experimentally on a 10 kVA breadboard
