An inverter system for a vehicle is provided. The system includes an energy storage that stores electrical energy and a first inverter that includes a plurality of first switching devices and converts energy stored in the energy storage into AC power. A second inverter includes a plurality of second switching devices that are different in types from the first switching devices, and is connected to the energy storage in parallel with the first inverter. The second inverter converts the energy stored in the energy storage into AC power. A motor is driven by the AC power converted by the first inverter and the second inverter. A controller generates a PWM signal based on required output of the motor and operates the motor by inputting the generated PWM signal to at least one or more of the first inverter and the second inverter.
