Abstract

This design introduces an adjustable frequency AC Supply which is used as the excitation source of the metal particle detection sensor. According to different sine table, STC15W4K16S4 microcontroller outputs corresponding frequency SPWM control signals. These signals are amplified by the MOSFET drivers. Then they drive the H-bridge inverter circuit. After the RC low-pass filter, the output frequency is from 2400Hz to 3000Hz, and the frequency interval is 50Hz. The output wave is sine AC voltage. This system can be used as the excitation source of metal wear particle detection sensor.
