Claim 0:
1. A control module of an inverter apparatus, the control module comprising:
a voltage controller configured to output a voltage control signal, based on an error value that is a difference between an AC output voltage of the inverter apparatus and a reference voltage wherein the voltage controller comprises one of a proportional integral (PI) controller, a proportional differential (PD) controller, and a proportional integral differential (PID) controller;
a damping controller configured to output a damping control signal by reflecting a virtual damping component corresponding to a value of a virtual damping resistor to the AC output voltage; and
a proportional controller configured to calculate, in consideration of an AC voltage output from an inverter circuit module in the inverter apparatus, a control signal for controlling the inverter circuit module from a signal obtained by subtracting the damping control signal from the voltage control signal.
