Specifically, the mains supply is subjected to voltage conversion through a voltage converter, and the mains supply voltage given in this step is 220V alternating-current voltage. The voltage converter in this embodiment is an AC-DC full wave rectifier for converting AC voltage mains into DC voltage.
