IGBT high frequency rectifier power supply

Product Overview IGBT high-frequency switching power supply is a new generation of DC power supply equipment based on high-frequency PWM pulse width modulation technology, using insulated gate bipolar transistor (IGBT) as the core power device. The basic working principle is as follows: three-phase alternating current is converted into smooth direct current after rectification and filtering, and then converted into high-frequency alternating current (usually 10kHz to 50kHz) by IGBT full-bridge inverter circuit. After step-up or step-down isolation by high-frequency transformer, the final rectifier filter outputs stable DC voltage or current. Compared with the traditional SCR phase-controlled power supply, IGBT high-frequency switching power supply will work from the frequency
