Description

This reference design provides isolated 24Vdc, 16Vdc (x3) and 6V outputs to power the control electronics, IGBT module and fan for 100Vac/200Vac input servo drives. The power supply can be either powered directly from a single or 3- phase AC mains or can be powered from the DC link voltage. This reference design uses primary-side regulation, quasi-resonant flyback topology and is rated for 30W output. The line and load regulation of the power supply is designed to be within 5%. The power supply is designed to meet the clearance, creepage and isolation test voltages as per IEC61800-5 requirements

Features
  • 30W isolated main power supply for servo drives
  • Can operate with DC Link (450Vdc max) or AC input (200VAC)
  • Load and line Regulation: 5%
  • Input UV/OV, Output overload & SC protection
  • Protection against loss of feedback
  • Lower system cost solution using UCC28711 through primary side regulation, eliminating feedback loop
  • Quasi-Resonant mode controller improves EMI
  • Operating temp range: -10ºC to 65ºC
  • Designed to comply with IEC 61800-5
