Abstract: According to the application of module power supply in electrophoresis production, this paper studies the module power supply for electrophoretic painting of key equipment in electro- phoresis production line, proposes an energy-saving module power supply based on IGBT/SiC MOSFET soft switching technology, and applies it to cathodic electrophoresis production line through distributed control through compatible industrial network. Through the application of soft switching technology to achieve zero voltage on, zero current off, switching frequency increase, single switching tube voltage tolerance value reduction and high voltage breakdown risk, so that the electrophoresis module power supply self-loss is greatly reduced, device voltage tolerance, equipment service life and module use efficiency is greatly improved, to achieve the effect of saving energy in electrophoresis production. From the perspective of technology foresight, it has certain scientific research value.
