Abstract
A driving apparatus configured to drive a plurality of switching elements including a first switching element and a second switching element, and each of the plurality of switching elements has a gate electrode. The driving apparatus includes: a driving circuit configured to supply a voltage to the gate electrode; and a controller configured to control the plurality of switching elements to turn on or off. The controller includes a control mode having a multi-driving mode configured to drive both of the first switching element and the second switching element, and a single driving mode configured to drive only the first switching element. The controller at the single driving mode sets a gate voltage to be applied to a gate electrode of the first switching element at a clamping voltage, which is smaller than the gate voltage of the first switching element at the multi-driving mode.
