PROJECT TITLE :

A Three-Phase Multilevel HybridSwitched-Capacitor PWM PFC Rectifierfor High-Voltage-Gain Applications - 2016

ABSTRACT:

In this paper, a three-phase multilevel power factor correction rectifier using the hybrid switched-capacitor concept is proposed. The converter is appropriate for top-voltage-gain applications from conventional three-part low-voltage sources. The 3-level voltage operation reduces the burden and bulk of the magnetic devices. The main benefits of the proposed converter are low number of active switches, high voltage gain, sinusoidal currents, low voltage stress across all elements, and easy control. Each steady-state and dynamic analyses are investigated. Experimental results for a 750zero-W/220-V-to-1600-V laboratory prototype with maximum potency of ninety seven.seventy eightp.c are presented and discussed.
