The stator of the alternator has a delta winding with each winding having twelve coils. Three diode bridges are provided with each bridge being connected to the junction of two of the windings. Each bridge has four positive diodes connected in parallel and four negative diodes connected in parallel. Two of the positive diodes of each bridge and two of the negative diodes of each bridge are connected to a first output member and the other two positive diodes and the other two negative diodes of each bridge are connected to a second output member. Two heat sink plates are connected to the inside of one wall of the alternator housing and a third heat sink plate is connected to the outside of the wall. Each plate supports diodes from three of the bridges.

DETAILED DESCRIPTION It is an object of the invention to provide an alternator that will provide the voltage and current required by a vehicle such as an ambulance to operate emergency equipment particularly during idle at low rpm.
It is a further object of the invention to provide means for dissipating the heat from the alternator to allow the diodes of the diode bridges to operate to produce a desired high output current.
The alternator of the invention uses a special stator winding, a specially wound rotor and three diode bridges each with eight diodes.
Four positive diodes of each bridge are coupled in parallel and four negative diodes of each bridge are coupled in parallel.
The diodes of each bridge are mounted on special heat sink plates secured on the outside and inside of the housing.
