Überblick

62.5W auxiliary power supply for three-phase power converter

The reference board was developed to support customers designing auxiliary power supplies for three-phase converters using the 1700 V CoolSiC™ MOSFET in a single-ended flyback topology. The board has three outputs of +15 V, -15 V and +24 V with up to 62.5 W output power working in a wide input voltage range from 200 VDC to 1000 VDC. The reference board works in quasi-resonant mode and has a peak efficiency of 90.56% at a full load specification.
