Design and Implementation of High-voltage Charging Power Supply for Battery

This article in view of the space craft high-voltage energy storage battery charge need high efficiency and high gain isolated DC-DC power supply requirements. It designs and implements a high voltage charging power supply with high efficiency. At the same time, completes magnetic isolation and phase shift control and introduces the double-closed loop control of voltage loop and current loop, realizes the constant flow of constant voltage charging ways. The input voltage of the rated state of the power supply is 100V, and the output voltage is 200V. Through experimental verification, the average working efficiency of the power supply charging is more than 93%.
