Design of STM32-based Adjustable High-voltage Driving Power Source for Dielectric Elastomer Actuators
In order to meet the voltage requirements of dielectric elastomers,a high-voltage power source with STM32 as the control core was designed.The power source employed a DC/DC buck converter featuring fewer peripheral compo-nents,simple circuit structure,and high conversion efficiency as the functional core.STM32 changed the voltage input to the high-frequency transformer and drove the transformer by adjusting the resistance change of the potentiometer and con-trolling the size of the duty cycle.The voltage and current data was acquired through ADC and was transferred using DMA to the OLED display screen.The actual voltage output could be adjusted through a serial port,with simple operation and strong applicability.
