The RC anti EMI absorption circuit module consists of a resistor and capacitor connected in series, placed in parallel with switching components. This setup enhances the voltage and current waveforms experienced by electronic power devices during switching operations. The circuit module helps protect switches like relays and thyristors from voltage spikes caused by inductive loads when switching on or off. It also reduces electromagnetic interference and improves the microcontroller’s resistance to electrical noise.
