Description

This reference design provides four isolated outputs of 24 V,15 V, –15 V, 8 V and maximum 150-W output with two-switch flyback topology. The power supply can be powered from 350-V to 1500-V DC input. This design uses the valley switching UCC28740 flyback controller . The design achieves 89.11% efficiency at 600-V input and 86.17% efficiency at 1500-V input, full-load condition.

Features

  • Wide input range from 350-V to 1500-V DC
  • Two-switch flyback topology recycles leakage energy
  • Quasi-resonant mode controller improves efficiency
  • Less voltage stress on the primary switch
  • Peak efficiency of 89.11% at 600-V input and 150-W output
  • 86.17% efficiency at 1500-V input and 150-W output

Typical applications

  • Central inverter; DC fast charging station; Fuel cell inverter; Power conversion system (PCS); Single phase string inverter; Three Phase String Inverter
