Development of high current power supply for electroplating

摘要

This paper describes the development of high current (up to 2500A) and low voltage(up to 12V) SMPS unit for electroplating. A special topology and structure of the inverter-transformer was developed. In such manner, the leakage inductance, shin effect and proximity effect of the transformer was greatly reduced. Based on the it, a 5000A/12V power supply was built by two units.
