Classification: CPC H  B | IPC B  H

Claim 7:
8. An inverter apparatus comprising:
an inverter circuit module configured to convert a DC input voltage into an AC voltage, and output the AC voltage;
a filter module connected to the inverter circuit module in series, and configured to supply an AC output voltage obtained by filtering the AC voltage to a load, the filter module including no damping resistor;
a control module configured to calculate a control signal for controlling the inverter circuit module by receiving a feedback on the AC output voltage; and
a switch driver module configured to control switching elements in the inverter circuit module to be turned on or off according to the control signal,
wherein the control module is configured to calculate 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.
