In order to ensure the normal operation of the ultrasound power supply, in addition to designing hardware protection circuits for various faults, software protection is also used. Protection is jointly implemented by hardware and software to ensure the reliable operation of the system. Software protection is achieved by filtering and sampling the detected signal and connecting it to the XINT2 interrupt level of the DSP. When a fault occurs, it enters the software interrupt program and blocks all PWM pulse outputs to achieve protection effect.

Due to the traditional switch transistor trigger circuit being controlled by hardware for pulse phase shifting, the circuit is complex, the components are prone to aging, and the output waveform is prone to varying degrees of distortion, which greatly affects the symmetry of the trigger pulse. A control system composed of microprocessors can complete control tasks in real-time and accurately under the premise of satisfaction. By using software to achieve phase shift control, the symmetry of trigger pulses can be greatly improved and signal accuracy can be improved. Here, DSP is used to achieve PS-PWM control of power. By changing the phase shift angle, a wide range of power regulation is achieved, and the power switching device operates in a soft switching state, greatly improving system efficiency, making it more flexible and reliable to operate.
