Abstract
A power source system for vehicles includes a transistor relay and a first triac to vary the amount of DC delivered to a field winding of a generator through a second triac, whereby stable AC and DC currents can independently be obtained.
Claims2
A power source system for vehicles, said system comprising:
- a generator including stator windings having a neutral point and a DC output terminal, and a field winding having a field winding terminal and a grounded terminal;
- a first triac connected across said DC output terminal of said generator and said field winding terminal;
- a first potentiometer, a gate of said first triac being connected to said neutral point of said stator winding through said first potentiometer;
- a second triac;
- a transistor relay;
- an intermediate point of said first potentiometer being connected through said second triac to both said transistor relay and to said neutral point of said stator winding, wherein said transistor relay and second triac operate to vary the rate of feeding of direct current to said field winding through said first triac, whereby stable alternating and direct currents are independently obtained.
