DIY Bench Power Supply With Old Computer SMPS : Hey! everyone My name is Steve. An NPT IGBT family has been developed and optimized targeting specifically SMPS applications. The target specification is as below. 1(b), the inductor winding is constructed using two wires, with a 1:1 turns ratio. But before using it we have to cope with some problems that can blow this device in seconds.
