FF 6592SHF R. 3117 IN THE UNITED STATES PATENT AND TRADEMARK OFFICE "SOLID STATE VOLTAGE REGULATED AUTOMOTIVE- TYPE ELECTRICAL POWER SUPPLY SYSTEM" ABSTRACT OF THE DISCLOSURE. A multi-phase generator has a separately excited shunt field which is controlled by a voltage regulator. A free- wheeling diode is connected in parallel with the field. The voltage regulator is included in a single, hermetically sealed housing which has a metal base plate forming one terminal of the voltage regulator; two insulated terminals project from the voltage regulator and are sealed, in insulated relation, through the housing, preferably the base plate. Three monolithic semi-conductor integrated circuit (IC) chips are located within the sealed housing, two of them soldered to the base plate so that one of the semi-conductor connections of the chip are directly connected to the base plate, the connection being for the collector of the power transistor and the anode of the free-wheeling diode, the control portion of the voltage regulator being secured to a ceramic plate which is attached to the base plate, other terminals from the voltage regulator are being effected internally, by bonding wires, and to the two externally excessible contacts, so that the entire assembly is simple, readily manufactured, and requires little assembly, labor and time for connection to an alternator structure.
