System and method for supplying power to at least one load
First Claim
1. A system for supplying power to at least one load, the at least one load coupled to at least one power source, the system comprising:
- a load bank coupled to the at least one power source and the at least one load, the load bank comprising a controllable voltage source comprising switches, at least three resistors coupled between an output side of the controllable voltage source and the at least one power source, and at least one storage element comprising one or more capacitors, batteries, or combinations thereof; and
a control device for controlling the switches during a first condition such that, to the extent that an output power of the at least one power source exceeds a requisite power of the at least one load, any excess output power is either supplied to the at least one storage element or consumed by the at least three resistors, wherein the control device comprises;
a power to voltage conversion unit for receiving a power command and converting the power command to a voltage command;
a subtractor for subtracting the voltage command from a voltage of the load bank; and
a control unit for generating switching commands for controlling operations of the switches to reduce a difference between the voltage command and the voltage of the load bank.

Abstract
It is a system for supplying power to at least one load. The system comprises at least one power source, load bank and control device coupled to the at least one load. The load bank is coupled to at least one power source and at least one load. The load bank comprises a controllable voltage source, at least three resistors coupled between an output side of the controllable voltage source and the at least one power source, and at least one storage element. The controllable voltage source comprises more than one switches. And the at least one storage element comprises one or more capacitors, batteries, or combinations thereof. The control device is configured for controlling the switches during a first condition such that, to the extent that an output power of the at least one power source exceeds a requisite power of the at least one load, any excess output power is either supplied to the at least one storage element or consumed by the at least three resistors. This invention also provides a method for supplying power to at least one load.
