Power supply unit (PSU) usually works to convert utility AC voltage into regulated DC voltages to be used by the equipment. In most PSU, the energy flow is controlled with semiconductors which are continuously switching on and off with high frequency. Such kind of PSU are referred to as switch mode power supplies or SMPS .
