UTILITY INTERACTIVE PHOTOVOLTAIC INVERTER SYSTEM WITH AN INVERTER FOR CONTROL, CAPABLE OF REDUCING OUTPUT DISTORTION DUE TO A HARMONIC CURRENT

摘要

PURPOSE: A utility interactive photovoltaic inverter system is provided to transmit an inverter voltage to a power system by improving output resolution of the inverter voltage.;CONSTITUTION: An inverter(110) for generating a voltage outputs a first inverter voltage by switching a first input voltage of an input power system. An inductor(120) for voltage interconnection is serially connected to the inverter for generating the voltage. The inductor for the voltage interconnection transmits a first inverter voltage to a power system. An inverter(130) for control is serially connected between the inverter for generating the voltage and the inductor for the voltage interconnection. The inverter for control outputs a second inverter voltage by switching a second input voltage of the input power system.;COPYRIGHT KIPO 2010
