The entire system of the digital ultrasonic circuit board circuit is generated by the STM32 main controller to generate PWM pulse signals, control the EXB841 to optimize the driving circuit, drive the high-frequency full bridge inverter circuit, and ensure the maximum power value acting on the output of the transducer through impedance matching and output current detection. At the same time, for ultrasonic transducers in different frequency bands, it is necessary to adjust the given input and keep the generator frequency tracking within a certain range of the frequency reference value
