Abstract
A power switch circuit includes at least one switch unit including at least one first switch and one second switch which are connected in parallel. A turning-on loss of the first switch is smaller than a turning-on loss of the second switch, a turning-off loss of the first switch is larger than a turning-off loss of the second switch; during one controlling period of the switch unit, when the switch unit is controlled to be turned on, a moment when the first switch is turned on is controlled to be earlier than a moment when the second switch is turned on; and when the switch unit is controlled to be turned off, a moment when the first switch is turned off is controlled to be earlier than a moment when the second switch is turned off.
