65W High Voltage Auxiliary Power Supply Reference Design

Overview

TopologyFlyback Converter
Input voltage300-1000 V
Output 124 V / 2.7 A
IC revision1.1

Description

For the power conversion system of three-phase power supply (400Vac~690Vac), a 65W/24V industrial auxiliary power supply evaluation board with a DC bus voltage range of 300Vdc~1000Vdc is designed. The use of PINJ 1700V SiC MOSFET (P3M173K0K3) can simplify circuit design, significantly improve efficiency, reduce the volume and weight of auxiliary power supply, and help industrial equipment achieve significant miniaturization, high reliability and energy saving.

Features

  • Over voltage protection
  • Input under voltage protection
  • Over current protection

Typical applications

  • EV-charger
  • UPS
