Infineon Technologies ICE5QSAG | Demoboard EVAL_12W_3PH_SMP7
12 W three-phase power supply for smart meters and home appliances
Overview
| Topology | Flyback Converter |
| Input voltage | 185-460 V |
| Switching frequency | 47-64 kHz |
| Output 1 | 12 V / 1 A |
| IC revision | 1 |
Description
This document is an engineering report describing a three-phase-input 12 V 12 W Flyback converter power supply using the ICE5QSAG QR Flyback controller and the new 950 V CoolMOS™ P7 SJ MOSFET IPD95R1K2P7, which are the latest generation of devices from Infineon. The converter is operated in Discontinuous Conduction Mode (DCM) with variable frequency, has a low standby power, and has various protection modes built in for a highly reliable system. This demo board is designed to evaluate the performance of the IPD95R1K2P7 for ease of use in applications such as smart meter power supplies. This board could also be used as an auxiliary power supply for home appliances such as air-conditioning units or induction cookers.
Typical applications
- Smart meter SMPS, AC/DC SMPS, AUX for home appliances
