Design of a switch-mode power supply with soft switching and analog control

Abstract : In high-power applications to meet high-efficiency and green standards. Some power-supply designers have found it easier to use a D/DC, full-bridge converter. This is because this kind of converter can obtain zero-voltage switching on the primary side of the converter reducing switching losses, and EMI and increasing overall efficiency. The purpose of this paper is the design of a switch mode power supply for industrial applications (vehicle battery charger, power supply for a helicopter…,). This Full Bridge DC/DC converter controlled by an analog control. This shows several advantages as simple implementation, compactness with satisfactory performance. The simulation results obtained are compared with a Full Bridge Converter controlled by UCC28950 which is a digital Texas Instruments component. The designed power supply operates with an efficiency of more than 90%.
