LIGHTING BALLAST FOR USE WITH VARIABLE DC POWER DISTRIBUTION
摘要
<p>Systems and methods are described for selectively applying DC power from a variable voltage DC power bus to a DC load. The ballast includes at least one switch coupled between the DC power bus and the DC load. A processor is coupled to the at least one switch and controls the operation of the at least one switch. A non-transient computer-readable memory stores instructions that are executed by the processor to control the operation of the processor. The processor determines a voltage on the variable voltage DC power bus and defines a pulse-width modulate power control signal based on the determined voltage. The at least one switch is then operated based on the pulse-width modulated power control signal to apply DC power from the DC power bus to the DC load at a first frequency.</p>
