Part Details:

STEVAL-ISA012V1 3 phase power supply with VIPer and Power MOSFETs Data Brief Features Minimum AC input voltage = 90 VAC Maximum AC input voltage = 450 VAC Time of hold up capability > 50 ms Mean input power < 6 W (in compliance with IEC62053-21) Input connections allowed: ­ 1-phase with neutral ­ 2-phase without neutral STEVAL-ISA012V1 ­ 3-phase with neutral VOUT1 = 5 V, IOUT1 = 10 mA Typical end applications for this solution can be VOUT2 = 3.3 V, IOUT2 = 100 mA found in the industrial market in the range below 5 Maximum precision error = 3% W, such as three-phase and single-phase power meters, industrial bias power supplies and Maximum ripple voltage = 50 mV auxiliary SMPS for high voltage street lighting, Line regulation = +/- 1% where the input voltage can range from 90 VAC to Load regulation = +/- 1% 450 VAC and 1000 V Power MOSFETs are currently used. Output power (peak) = 550 mW Description 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 three-phase 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.
