Filed: 1997-03-21
Abstract: The current in a field winding (102, Fig.4) of a vehicle A.C. generator (1) which charges a battery (5) is controlled by a semiconductor switching device 301 having a collector coupled to a field winding terminal b and via a diode 302 to a power source terminal a , an emitter coupled to a ground terminal d , and a base coupled to a terminal c which receives a control signal from a control circuit (4) responsive to the battery voltage. A ground pattern ( e , Fig.1) is connected to ground terminal d and extends intermediate power source terminal a and control signal terminal c , whereby if a short circuit is produced, eg. due to ingress of water, short circuit current will flow from terminal a into the ground pattern ( e ) rather than into the control terminal c , thus preventing erroneous conduction of the switching device 301 which could give rise to overvoltage and battery overcharge. A ground pattern ( f ) may surround the control terminal c . Alternatively, the control terminal c may be arranged on a ground pattern g with an insulating layer h therebetween. An alternative arrangement has a pattern connected to the power source terminal, rather than a pattern connected to the ground terminal.
