Abstract
In a driver having a reference point with a reference potential for driving a target switching element having an on-off control terminal, a charging path electrically connects the on-off control terminal of the target switching element and a driving power source for charging the on-off control terminal of the target switching element. A bypass path electrically connects the on-off control terminal of the target switching element and the driving power source. A storage has a first conductive end electrically connected to the bypass path and a second conductive end electrically connected to the reference point of the target switching element, and is configured for storing therein charge sent through the bypass path.
