A kind of variable voltage variable frequency high-voltage power supply system was manufactured by using IPM（intelligent power module）,SG3526（voltage pulse width modulated chip） and UC3846（current pulse width modulated chip） as main elements.The system consisted of single phase rectification wave filter circuit,Buck DC/DC voltage regulation circuit,DC-AC inverter circuit etc modules.The system is simple in structure,small in switching power supply loss,low in noise,small in volume and mass with self-driving ability,short-circuit protection,less voltage protection,over current protection and over heating protection.The driving circuit adopted modular design with small internal leads inductance,which made the system more stable.
