ABSTRACT:
A voltage regulator for use with a source, such as a generator, and a load, such as a battery for limiting the current delivered by the source to the load at one of a plurality of selectable current limit levels. The regulator comprises a regulation circuit, an over voltage protection circuit and a current limiting circuit. The current limiting circuit includes a shunt resistor to sense the current flowing between the source and the load and a switch to permit selection of a single limit level from the plurality of limit levels. The switch may be manually or automatically controlled. The current is limited by generating an over current signal to the over voltage circuit which, in response, reduces the output of the source.
