Dualvoltage Power Supply System based on Y-Source Bidirectional DCDC Converter

摘要

In order to improve the stability and the gain of traditional bidirectional DC-DC converter, a new bidirectional Y-source DC-DC converter is proposed. The new type converter has the advantages of small size, small weight, high voltage gain, stable input voltage and continuous input current. This paper analyzes the working process of the new type of converter in power forward transmission and power reverse transmission, adopts PWM method to control IGBT switch, and verifies the rationality of this new type of converter by Matlab/Simulink simulation.
