Description

technical field [0001] The invention relates to the field of power adjustment, in particular to a digital high-precision power adjustment system and adjustment method Background technique [0002] In the field of ultrasonic applications, such as ultrasonic atomization or ultrasonic knife, etc., it will contain an essential part, that is, the power amplifier module. In the existing power amplification technology, the half-bridge inverter scheme is mostly used. [0003] As we all know, full-bridge inverters are suitable for high-power inverters, hundreds of watts or even kilowatts, and half-bridge inverters are suitable for low-power inverters. Even low-power inverters are basically more than ten watts or even tens of watts. It is not suitable for application scenarios with even smaller tiles. [0004] The half-bridge inverter is composed of many discrete components, the circuit design is complex, and its performance is also affected by the discrete components. The inverter ...
