Document Type and Number:
WIPO Patent Application WO/2022/082426
Kind Code:
A1
Abstract:
A power conversion device (200), includes a bulk capacitor (115), a current limiting resistor (151) in series with the bulk capacitor (115), and an inrush current control device configured to bypass the current limiting resistor (151) when activated. The power conversion device (200) also includes a bypass device (210) in parallel with the current limiting resistor (151), configured to provide a low-resistance path to the bulk capacitor (115) during a power surge.
