Claim 13:
14. A method performed in an inverter apparatus, the method comprising:
converting a DC input voltage into an AC voltage and outputting the AC voltage;
supplying, by a filter module of the inverter apparatus, an AC output voltage obtained by filtering the AC voltage output from an inverter circuit module of the inverter apparatus to a load, the filter module including no damping resistor;
calculating, by a control module of the inverter apparatus, a control signal for controlling the inverter circuit module by receiving a feedback on the AC output voltage; and
controlling, by a switch driver module of the inverter apparatus, switching elements in the inverter circuit module to be turned on or off according to the control signal,
wherein the calculating of the control signal comprises calculating the control signal by reflecting a virtual damping component corresponding to a value of a virtual damping resistor, and
wherein the inverter apparatus is included in a vehicle to load (V2L) system, and wherein the DC input voltage is a DC link voltage.
