Abstract
A regenerative direct current (DC) load includes an input circuit, an output circuit, a low pass filter circuit, and a current regulating circuit. The input circuit is configured to receive electrical power. The output circuit is configured to provide electrical power. The low pass filter circuit is electrically coupled to the output in series. The current regulating circuit is configured to regulate a current of the electrical power. The current regulating circuit is electrically coupled to the input. The current regulating circuit includes a first switch, and a first control circuit. The first switch is electrically coupled between the input circuit and ground. The first control circuit is configured to sense the current and adjust a cycle duration and/or duty cycle of the first switch based upon the sensed current.
