Title:
POWER CONDITIONER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/199042
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a power conversion system with which it is possible to reduce an inrush current to a capacitor during startup of a DC power supply. A power conversion system (1) comprising a first capacitor (C10), an insulation-type converter circuit (2), and a control circuit (6). The first capacitor (C10) is connected to a DC power supply (8) with an inrush current prevention circuit (7) interposed therebetween. The inrush current prevention circuit (7) is capable of switching between at least a high-impedance state and a low-impedance state. The converter circuit (2) includes a transformer (23), the first capacitor (C10) being connected to a primary winding (231) of the transformer (23). The control circuit (6) controls the inrush current prevention circuit (7) and the converter circuit (2), and after starting operation of the converter circuit (2), switches the inrush current prevention circuit (7) from the high-impedance state to the low-impedance state.
