Abstract: A power transistor monolithic integrated structure produced by a bipolar-epitaxial technology includes a plurality of parallel connected transistor cellular structures each containing at least one component transistor. The base of each component transistor is coupled to a common base control conductor via a protective resistor and a fuse link which melts in the event of a defect in the transistor cell. Another fuse link is incorporated in the branch conductors leading from the collectors of respective component transistor to a common conductor web mounted on the surface of the transistor chip. All transistor cellular structures are electrically isolated one from each other during the manufacturing process.

Abstract: A voltage regulator (4) for a generator (1), particularly for use in motor vehicles, is provided which produces an average field current in the exciting winding (2) of the generator (1) by switching on and off the field current by a controlled semiconductor switch in cooperation with a recovery diode in such a way that the generator voltage remains approximately constant independently of the load and the speed. The voltage regulator (4) contains an integrally acting component for compensating for load-dependent and speed-dependent errors, which component is produced by a nonlinearly working integrator for the relative turn-on period of the current through the exciting winding (2) and is fed back into the regulating circuit of the voltage regulator (4). The nonlinearly of the output variable of the integrator is produced in that, for the formation of the correction function, one period portion during the current flow through the exciting winding (2) of the generator (1) and the controlled semiconductor switch is evaluated differently than the other period portion during the current flow through the exciting winding (2) and the recovery diode.

Abstract: A voltage regulator for generators is proposed which, compared with a voltage regulator known, for example, from DE-PS 27 38 897, is supplemented in such a manner that an integral component corresponding to the relative operating time of the field current is formed and this component is fed into the actual control loop. The relative operating time of the field current in this arrangement can be obtained more or less directly from the switching characteristic of the switching transistor (20) for the field current or by means of a sensing resistor (33) in series with the exciter winding (21).

Abstract: To improve the regulating response of an automotive-type, solid-state voltage regulator and render it essentially immune to ripple while additionally permitting complete integration of the entire voltage regulator without external discrete filter capacitors, a difference amplifier has the output voltage of the on-board vehicle network, for example from an alternator, applied thereto for comparison with a reference, the difference amplifier, respectively, controlling a capacitor charge current supply and a discharge current drain circuit, both connected to a small capacitor in the order of, for example, only 30 pF which, hence, can be integrated, the voltage across the capacitor being sensed in a high-low window or range-type discriminator which has a dual-state output to control conduction or non-conduction of a transistor in series with the field of the alternator in dependence upon whether the voltage across the capacitor, as it is being charged or drained, is above an upper threshold or below a lower threshold of the discriminator. Preferably, the circuit includes current mirror circuits in which currents in one branch are reflected in another to provide for balance, temperature compensation, and to render the circuit immune to variations in loading on the alternator.

Abstract: To provide for uniformity of power dissipation in the components of the switching system, regardless of the duty cycle upon repetitive, cyclical operation, the coupling resistors connected to the driver transistor and to the power transistor are so dimensioned relative to each other, and to the internal resistances of the driver transistor and the power transistor of the system that, in an initial approximation, the dissipation losses arising in the system are independent of the duty cycle of the switching transistor; this is obtained by selecting the sum of the resistance value of the collector resistor for the driver transistor and the base transistor of the power transistor such that (a) when the driver transistor is blocked, current flowing to the base of the power transistor holds the power transistor in full, saturated conduction and (b) the value of the collector resistor for the driver transistor is so selected that, when the driver transistor is conductive, the sum of the dissipated power in the collector-emitter path of the driver transistor, and in the collector-resistor of the driver transistor is approximately equal to the sum of the power which is dissipated in the collector resistor of the driver, the base resistor of the power transistor and the collector-emitter path of the power transistor, when the driver transistor is in blocked state. The entire system can be constructed on a monolithic chip and has a particular application as the switching circuit in automotive voltage regulators.

Abstract: The power supply system for a motor vehicle, includes a battery; a three-phase generator; a connecting line connecting the terminals of the generator and the battery; a rectifier connected electrically to the generator; a voltage regulator for switching an exciter field of the generator on and off to control a voltage actual value at the generator terminals and producing an average field current in the exciter field to maintain a power supply voltage substantially constant regardless of load and speed; and a circuit device for determining and for partially compensating an undesirable direct voltage drop at the generator terminals resulting from a voltage drop in the connecting line caused by load current. The device for determining and for partially compensating is structured to determine an alternating voltage at the generator terminals produced by an alternating current component in the connecting line. The circuit device for determining and partially compensating the voltage drop can include an integrator connected to a full-wave rectifier and a function generator connected to the rectifier. The integrator, full-wave rectifier and function generator are connected in series between the generator terminals and the battery in the connecting line.

Abstract: A controlled main switch, typically a semiconductor switch, is connected in parallel to the load. In accordance with the invention, an auxiliary switch, typically also a semiconductor switch such as a switching transistor is directly connected across the terminals of the load, and with an impedance, for example a resistance, diode, or Zener diode to the main switch, and controlled to switch in synchronism with the main switch, so that the residual voltage across the load due to inherent voltage drop across the terminals of the switch becomes a minimum. Integrated technology may be used, combining preamplifiers and distribution networks in one monolithic chip.
