An electric generating system for automobiles has a primary generator which is driven by an internal combustion engine of an automobile and supplies power to an electric load of the automobile and an electric motor for driving wheels of the automobile which are not driven by the internal combustion engine. A secondary generator is driven by the internal combustion engine and drives the motor. A control unit controls the secondary generator and the electric motor. The control circuit controls the output of the generator according to a driving force requested by the automobile, and the driving force of the electric motor is controlled by the output of the secondary generator.

One slot arranged between two slots containing a first armature winding contains a second armature winding for a phase different from a phase of the first armature winding; one slot arranged between the two slots containing the first armature winding contains a third armature winding for a phase equal to the phase of the second armature winding; and, one of the second armature winding and the third armature winding is arranged in a coil end portion in an outer peripheral side of the first armature winding, and the other is arranged in an inner peripheral side of the armature winding. With this, the projected height of the coil end portion of the stator can be reduced.

A control device for a battery charging AC generator for a motor vehicle including a power transistor connected in series with a field winding of the AC generator for performing switching control of a current flowing through the field winding. A voltage deviation circuit detects a deviation of the battery voltage from a reference voltage; and a PWM signal generating circuit is responsive to a voltage deviation signal from the voltage deviation circuit for turning the power transister on and off a resistor connected in series with the power transistor detects a current flowing through the field winding; and a current limiting circuit generates a turn off signal for the power transistor when the detected current is determined to have exceeded a reference current. A latch circuit operates in response to a clock signal from the PWM signal generating circuit to limit the frequency of turning on and off of the power transistor to below 1 KHz.

A vehicle alternator output rectifier instrument in which mesa structure Zener diodes, formed by diffusion of impurity on a P-type silicon substrate, are used as rectifier elements which are used in rectifier circuits for rectifying an alternate current output of a vehicle alternator. Since the vehicle alternator output rectifier instrument employs the above Zener diodes, this rectifier instrument can endure high temperature circumstances, considerably reduce a reverse leakage current to thereby prevent a battery voltage from being discharged and reduce a radio noise to thereby reduce a bad influence exerted upon an electronic device serving as a load.

An AC generator comprises a rotor and a stator having a three-phase winding. A three-phase inverter is connected to the three-phase winding. Here, the three-phase winding comprises at least two independent three-phase windings. Switching elements for respective phases of the three-phase inverter are connected in parallel by the number of the independent three-phase windings, and in-phase windings are individually connected to their parallel switching elements.

One method of achieving the above subjects is by connecting one of electroconductive members 12, which are pre-connected to the top and bottom of a semiconductor chip 11 and have thermal conductivity, to an electroconductive member 13, which is used with the semiconductor chip 11 to constitute a laminated structure, in electrically insulated form on the same surface as the installation surface of the electroconductive member 13 so as to straddle the laminated structure constituted by the semiconductor chip 11 and the electroconductive member 13.
