An inverter comprising:
- an inverter unit including a plurality of inverter arms, respective inverter arms including a high-side switch and a low-side switch connected in series between an input terminal at which an input voltage of a predetermined level is received and a ground, and switch the input voltage so as to output alternating current power;
- a gate driving unit including a multi-channel gate driver that receives instruction signals to instruct switching control of the plurality of inverter arms and output control signals to control the switching of the plurality of inverter arms, and a plurality of gate drivers configured to receive a switching control signal for the high-side switch of one of the plurality of inverter arms from the multi-channel gate driver and output a signal corresponding to the received control signal to the high-side switch;
- and
- a balancing unit configured to divide voltage applied to the plurality of gate drivers between the multi-channel gate driver and respective gate drivers among the plurality of gate drivers, according to the switching of the high-side switches, and maintain the divided voltage between the multi-channel gate driver and respective gate drivers among the plurality of gate drivers.
