Three-phase sinusoidal current rectifier with zero-current switching

This paper presents a three-phase rectification scheme with nearly sinusoidal line currents. The principle of third harmonic current circulation is used to reduce the distortion in the line currents. Zero-current switching is accomplished with the use of only two switches. A circuit design along with the experimental results are presented. Comparisons between a zero-current switching rectifier and a rectifier using hard-switched converters in terms of component ratings and EMI filter considerations are included.<
