Vehicle power generating system and method for controlling the same
First Claim
1. A power generating system comprising:
- storage means for storing electrical energy therein;
a synchronous power generator having a rotor for producing field magnetic flux and a stator with armature windings disposed thereon to produce a power-generating voltage;
AC-DC power converting means for rectifying a power-generating voltage outputted from said armature windings as generated power and supplying at least a first portion of said generated power to said storage means; and
control means for adjusting said power-generating voltage produced by said synchronous power generator to a first voltage for charging said storage means and a predetermined second voltage different from said first voltage;
wherein said control means is connected to said AC-DC power converting means and is further for receiving at least a second portion of said generated power from said AC-DC power converting means and for supplying said at least a second portion of said generated power as a leading phase current preceding in phase a phase voltage to said each armature winding when said control means adjusts said power-generating voltage to at least said second voltage.

Abstract
A power-generating voltage outputted from a vehicle synchronous power generator is adjusted to a first voltage for charging a battery under the control of a field current. Further, a leading phase current that leads a phase voltage is supplied to each of multiple armature windings and the field current is supplied to the field winding, whereby the power-generating voltage can be adjusted to a second voltage higher than the first power-generating voltage. Owing to the above construction, a voltage higher than the normal voltage can be generated by supplying each leading phase current from the vehicle synchronous power generator; hence power can be supplied to a high-voltage load based on the generated high voltage.
