  • Patent number: 10506675
    Abstract: A power supply system includes a power supply circuit and an output unit. The power supply circuit generates a pulsating voltage. The output unit is to be connected to a pair of electric wires to apply the pulsating voltage to the pair of electric wires. The power supply circuit generates the pulsating voltage such that the pulsating voltage has a full-wave rectified waveform obtained by full-wave rectifying an alternating voltage as a wave alternating between a positive voltage and a negative voltage.
