An electrical circuit for a power converter includes a first switching device proximate an AC source. The circuit also includes a voltage measurement device proximate a DC link and extends between the AC source and the DC link. The circuit further includes a DC voltage source and a first capacitive device. The first capacitive device is positioned between the first switching device and the voltage measurement device. The circuit further includes a second switching device positioned between the first capacitive device and the voltage measurement device. The circuit also includes a controller operatively coupled to the DC voltage source, the voltage measurement device, and the switching devices. The controller is configured to open the second switching device when a measured voltage signal generated by the voltage measurement device is substantially representative of a reference voltage value.
