Title:
INVERTER, POWER GENERATION SYSTEM, AND METHOD FOR INHIBITING THE DISTORTION OF HARMONIC WAVES
Document Type and Number:
WIPO Patent Application WO/2019/206289
Kind Code:
A1
Abstract:
The present application provides an inverter, a power generation system, and a method for inhibiting the distortion of harmonic waves. the inverter comprises an inverter circuit; an AC filter, the input port of said AC filter being connected to the output port of the inverter circuit; an AC electromagnetic interference (EMI) filter; a first AC switch, connected between the output port of the AC filter and the input port of the AC EMI filter; the AC filter comprises a first split capacitor, the first split capacitor being arranged between the first AC switch and the input port of the AC EMI filter; when the first AC switch is in a disconnected state, the first split capacitor is disconnected from the output port of the AC filter and the first split capacitor is connected to the circuit in which the AC system connected to the output port of the AC filter is located, thus suppressing harmonic distortion of the AC system. The embodiments of the present application are capable of suppressing harmonic distortion of an AC system.
