Abstract
An inverter system for a vehicle may include an energy storage device configured to store electrical energy; a first inverter including a plurality of first switching elements, and converting the energy into AC power; a second inverter including a plurality of second switching elements different from the first switching elements, being connected to the energy storage device in parallel with the first inverter, and converting the energy into AC power; a motor driven by receiving the AC power; a PWM signal generating device configured to generate a reference Pulse-width modulation (PWM) signal for controlling driving of the motor; and a PWM signal converting device configured to convert the reference PWM signal into both a first PWM signal input into the first inverter to drive the first switching elements, and a second PWM signal input into the second inverter to drive the second switching elements.
