Abstract

A power device is provided. The power device includes a current limiting resistor in series with a load, the current limiting resistor configured to provide a first current path to the load. The power device also includes an inrush current control device configured to provide a second current path to the load, the second current path configured to bypass the first current path in response to the inrush current control device being activated. The power device also includes a bypass device configured to provide a third current path to the load, the third current path configured to provide a low-resistance current path to the load during a power surge.
