1. A power distribution system comprising:
- a DC bus supplied by an electrical generator;
a resistive load connected to the DC bus; and
a switching device connected to the DC bus and the load, wherein the switching device is configured to periodically open the circuit between the resistive load and the DC bus for a reoccurring period of time, and wherein the switching device senses the load on the DC bus and changes the length of the period of time based on the sensed voltage.

Abstract
A power distribution system comprises a DC bus supplied by an electrical generator and a resistive load connected to the DC bus. A switching device connects to the DC bus and the load and is configured to periodically open the circuit between the resistive load and the DC bus for a reoccurring period of time. The switching device senses the load on the DC bus and changes the length of the period of time based on the sensed voltage.

9. A power distribution system for a marine vessel comprising:
-
a DC bus configured to be supplied by either an electrical generator or a rectified output from an AC power source, wherein the DC bus is configured to supply power to an appliance including a resistive heating element, the appliance being connected to the DC bus via an electromechanical switch including two contacts, wherein the electromechanical switch is designed to operate with an AC power supply; a switching device connected between the DC bus and the appliance, wherein the switching device is configured to periodically open the circuit between the resistive load and the DC bus for a reoccurring period of time in order to quench an arc forming between the contacts of the electromechanical switch;
wherein the switching device is configured to sense the load on the DC bus and changes the length of the period of time based on the sensed voltage. - View Dependent Claims (10, 11, 12)
