Average current control of three-phase PWM boost rectifier

Abstract

Average current control of three-phase PWM boost rectifiers with three linear current compensators and six-step PWM is a very attractive solution for its simplicity. The performance of the closed-loop control depends on the compensator design. This paper presents a modeling, analysis and design procedure for the average current control scheme. The current compensator design is verified experimentally on a high-frequency 6 kW boost rectifier, through current waveforms.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
