Converter for a DC power supply having an input resistance in series with a DC regulating circuit
First Claim
1. A vehicle having a vehicle body, a DC electric power supply of the vehicle mounted in the vehicle body, and a DC power converter, said converter converting a DC input voltage supplied by said DC power supply to generate a DC output voltage which is lower than said DC input voltage, and said converter comprising:
- at least two input terminals electrically connected across said DC power supply;
an input resistance electrically connected to one of said input terminals; and
a DC regulating circuit, electrically connected to said input resistance and to a further one of said input terminals, with said DC regulating circuit and said input resistance in series between said input terminals;
the input resistance and the DC regulating circuit being housed in first and second separate heat dissipative housings, said first housing dissipating heat generated by the input resistance and the second housing dissipating heat generated by said DC regulating circuit;
said first housing being mounted at a first location on said vehicle, and said second housing being mounted at a second location on said vehicle, said second location being different and spatially separated from said first location, whereby heat generated by said input resistance and dissipated by the first housing does not impair the operation of said DC regulating circuit; and
the DC regulating circuit having at least one output electrical connector device for connection to a load external to the first housing and the second housing such that said DC regulating circuit can transmit at least several watts of power to said load through said electrical connector device in the form of said DC output voltage.

Abstract
A converter is provided for stepping-down a DC power input to produce a DC power output of lower voltage. The converter includes a regulating unit (3), and in series with it an input resistor (4). In use, the resistor (4) is separated from the regulating unit (3) and is mounted on a body of a piece of machinery, so that heat produced within the resistor is transmitted to that machinery, and does not interfere with the operation of the regulating unit (3). The regulating unit (3) employs a linear conversion circuit which produces a stable (DC) output but, unlike conventional DC-DC converters, generates substantially no stray electromagnetic fields.
