Study of a Unidirectional Hybrid Three-Phase Voltage Source Rectifier

摘要

This paper studies a unidirectional hybrid three-phase voltage source rectifier (UHTPVSR), improves the topology, and the power distribution method of UHTPVSR. The Euler-Lagrange mathematical models of the boost converter and VIENNA rectifier are set up. A hybrid control strategy based on passive control is proposed. The hybrid control strategy makes UHTPVSR having good current tracking ability, strong robustness, and is easy to implement. The simulation results show that UHTPVSR can realize voltage control at DC side and achieve sinusoidal current and unit power factor at AC side, and are able to distribute power at predetermined rate.
