In order to improve the output waveform stability and control accuracy of power supply for shaking table,an improved control scheme based on PID algorithm and SPWM modulation is proposed. The overall framework of the shaking table power control system includes controller, rectifier, inverter, filter and communication modules. The control circuit adopts PID controller, and uses frequency doubling SPWM modulation to convert the output of the controller into the control signal of the inverter circuit to realize high-precision control of the power output. The simulation results show that the voltage and current output waveform of the power supply is stable, which verifies the effectiveness of the scheme in this paper.
