The switch applies the voltage rising waveform having a first slope by being repeatedly turned on/off according to a first control signal during the idle period, and/or the switch applies the voltage rising waveform having a second slope (having a higher gradient than the first slope) by being repeatedly turned on/off according to a second control signal during the first period.
