85 - 115-Vac input to isolated three-output flyback reference design for washing machines

Overview

TopologyFlyback Converter
Input voltage85-115 V
Output 115 V / 0.02 A
Output 224 V / 0.5 A
Output 312 V / 1 A

Description

This is a quasi-resonance (QR) flyback reference design for industrial applications, which illustrates how to convert AC input voltage 85 - 115 Vac to isolated multiple outputs: 24 V/0.5 A, 12 V/0.9 A and 15 V/20 mA using the UCC28600 Controller. The quasi-resonant switching of the UCC28600 allows this design to achieve peak efficiency of up to 87.5% while the no-load losses are less than 82 mW.

Features

  • Generates multiple isolated output voltages which mitigates noise between outputs
  • Enables standby operation with low power consumption (less than 82 mW) at no load
  • Provides efficient power conversion with greater than 87.5% peak efficiency
