100/200Vac Input, 30W Isolated Power Supply Reference Design for Servo Drives
Overview
| Topology | Flyback Converter |
| Input voltage | 40-320 V |
| Output 1 | 24 V |
| Output 2 | 16 V |
| IC revision | A |
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
Remarks- BOM & Schematic is added EVM pdf
30W isolated main power supply for servo drivesCan operate with DC Link (450Vdc max) or AC input (200VAC)Load and line Regulation: 5%Input UV/OV, Output overload & SC protectionProtection against loss of feedbackLower system cost solution using UCC28711 through primary side regulation, eliminating feedback loopQuasi-Resonant mode controller improves EMIOperating temp range: -10ºC to 65ºCDesigned to comply with IEC 61800-5
Typical applications
- Servo Drives
- Variable Speed AC/DC Drives
- Industrial Inverters and Solar Inverters
- UPS Systems
