STMicroelectronics 1500V MOSFET based DEMOBOARDS MPA Systems Lab – Power Supply Team
2 SMPS for 3-Ph Input 1500V MOSFET The SMPS have been designed for industrial applications for auxiliary power supplies; The input voltage in such applications can range between 230Vac and 460Vac; The proposed power supplies are based on the high voltage power MOSFET, with VDS=1500V; The power supply topology is the Quasi-resonant Flyback, driven by the primary controller L6565; Two demoboard have been developed: -DB#1 – 10W SMPS with two isolated outputs -DB#2 – 40W SMPS with double output
