Abstract
A current regulator for regulating alternating current (AC) flow to a load device is provided. The current regulator can include an AC coupling device that can be electrically connected to the load device via an output electrical path, a current control device electrically connected in series with the AC coupling device, and an AC feedback circuit electrically connected to the output electrical path and the current control device. The current control device can modify a current flow through at least one component of the AC coupling device in response to receiving an error correction current. An output AC current provided to the load device can be controlled based on the current flow through the component of the AC coupling device. The AC feedback circuit can include voltage error compensation device that provides the error correction current in response to receiving a feedback voltage corresponding to the output AC current.
