HIGH FREQUENCY PWM TECHNOLOGY

High frequency inverter front stage output

The high-voltage output generated by the front-stage transformer passes through the high-frequency transformer to output high-frequency alternating current, and then a high-frequency hundreds of V direct current is output to the back-stage mosfet/IGBT through the fast recovery diode full bridge rectification, and then the back-stage IC generates 50Hz control signal which is used to control the work of the mosfet/IGBT of the subsequent stage, and then output 120v/ 220v/ 230v/ 240v V 50/60Hz alternating current.
