Design and research of high-power signal generator based on STM32

This paper introduces a multifunctional signal generator based on STM32 microcontroller for ground electric field detection applications. The signal generator can output a variety of waveforms such as sine wave, triangle wave and square wave, the highest output voltage can reach 600 V, and the frequency can be adjusted within 2 Hz. Through careful design, the signal generator can generate the output waveform with small harmonic components, which is helpful to improve the precision and accuracy of geoelectric field detection. The experimental results show that the designed signal generator has good performance and stability in the ground electric field detection, and has high application value and practicability. The design and application of the signal generator provide a new and efficient detection method for the field of ground electric field detection, which has broad application prospect and popularization value
