Abstract
A power conversion device is provided. The power conversion device includes a bulk capacitor, a current limiting resistor in series with the bulk capacitor, and an inrush current control device configured to bypass the current limiting resistor when activated. The power conversion device also includes a bypass device in parallel with the current limiting resistor, configured to provide a low-resistance path to the bulk capacitor during a power surge.
