PROJECT TITLE :
A Bidirectional Three-Phase Push–Pull Converter With Dual Asymmetrical PWM Method
This paper proposes a brand new bidirectional 3-phase push–pull converter that has a easy structure and achieves zero-voltage switching turn-on of switches. Conjointly, because of use of a single inductor, an imbalance among section currents on the low-voltage high-current facet is trivial in the proposed converter though no current sharing control is utilized. In this paper, a new twin asymmetrical pulse width modulation (PWM) switching technique is proposed for bidirectional power flow management with seamless mode amendment. The proposed switching technique offers reduced circulating current and makes the converter easier to implement compared to the PWM plus part shift-based mostly control method since it's a general PWM technique having 2 independent duty cycle controls on each side. Experimental results from a three-kW prototype are provided to validate the proposed concept.
