A swept frequency ultrasonic IGBT circuit board. Background technology: Most existing ultrasonic power supplies use IGBT power transistors as the main power conversion devices. Generally, pulse transformers are used as driving circuits at low costs, while imported IGBT specialized driving modules are used for driving at high costs. The ordinary pulse transformer drive requires high winding requirements. Due to factors such as leakage inductance, the signal pulse output by the pulse transformer has a long rise and fall time, which leads to cross loss of the IGBT, resulting in high heat generation and low efficiency, and is easily damaged.
