Document Type and Number:
WIPO Patent Application WO/2012/114469
Kind Code:
A1
Abstract:
An inverter (1) that is applied to a solar power generation system (10) connected to a system bus (7) and that measures the system voltage (Vr) of the system bus (7), detects voltage drops in the system bus (7) on the basis of the measured system voltage (Vr), and, if a voltage drop is not detected, controls the DC voltage (Vdc) using an MPPT (22), and, if a voltage drop is detected, controls the DC voltage (Vdc) to increase, without using the MPPT (22).
