摘要： In an inverter system, a phase adjusting unit configured to adjust, according to reception timing of first data, a phase of second PWM carrier to match a phase of first PWM carrier. A master inverter further includes an amplitude adjusting unit configured to adjust, when second data is received by a communication unit, according to the received second data, amplitude of a first command voltage to balance an actual output current output from a master inverter to the motor and an actual output current output from each of one or more slave inverters to the motor.
