When only a single phase AC voltage is available and a load is a three phase motor, a static phase converter is used to provide power to initially start the motor. Once running, the static converter is disconnected and the motor continues to operate off the single phase. Two of TDK-Lambda’s baseplate cooled power modules, the 28V output PFE500SA-28 and the 360V output PF1000A-360, are being used in static phase converters for railway stations. Technical support and cost effectiveness were the primary reasons for the selection.
