STEVAL-ISA012V1

3 phase power supply with VIPer and Power MOSFETs
  • NRND NRND

This reference design represents a cost effective solution for low power high voltage power supplies. It has been developed to cover applications requiring an ultra-wide input voltage range (between 90 and 450 VAC), typical of threephase applications. This requires the use of very high voltage components, which increases cost, size, weight and the overall complexity of the power supply. The circuit includes a switching transistor connected between the input rectifier and the DC bulk capacitor (STMicroelectronics patent). The series switch limits the DC input voltage of the power converter by means of a driving circuit; thus the SMPS primary transistor can be selected as a standard part as well as a smart power primary IC.

Typical end applications for this solution can be found in the industrial market in the range below 5 W, such as three-phase and single-phase power meters, industrial bias power supplies and auxiliary SMPS for high voltage street lighting, where the input voltage can range from 90 VAC to 450 VAC and 1000 V Power MOSFETs are currently used.
