The design of a gate drive circuit for inverter DC12V to AC220V

Abstract

This paper presents the design of a gate drive circuit for inverter DC12V to AC220V, providing additional details from the 46th Electrical Engineering Conference [1]. The designed circuit uses both NPN and PNP transistors. Other components used are basic electronic devices that are easily obtainable, ensuring a continuous supply of components when mass-producing the product. Additionally, using transistors results in a lower cost compared to using integrated circuits (ICs). Testing the circuit showed that the designed gate drive circuit for the 12V DC to 220V AC inverter can drive an iron-core transformer with a PWM wave at a high frequency of 110kHz. The higher frequency allows for a smaller and cheaper design of the high-frequency signal filter circuit. This circuit design is well-suited for a 500W inverter.
