摘要： A reference voltage generator having a dual slope temperature characteristic, for use in an automotive alternator voltage regulator, comprises a bandgap circuit (R1,R2,R3,R4) which generates a voltage (A) having a thermal drift coefficient of zero and a voltage (B) having a non-zero thermal drift coefficient. These voltages are applied to a voltage divider (R5,R6) and a voltage-follower type of circuit (OPA1). A unidirectional conduction amplifier circuit (OPA2) has an input terminal connected to an intermediate point (C) on the voltage divider. A second voltage divider (R7,R8) is connected between the output terminals of the voltage-follower circuit (D) and the amplifier circuit (E) . An intermediate node (F) of the second voltage divider is coupled to an output terminal (VREF) of the generator.

摘要： In a voltage regulator for an alternator which charges a battery via a charging cable and supplies a vehicle mains with voltage, the output voltage is regulated as a function of the temperature of the battery. The voltage regulator has a power part and a control part, which includes a simulation device for storing data and for determining the temperature of the battery, and hence the optimum charging voltage, by simulation from the stored data. Further, the voltage drop between the alternator and battery can be calculated from the alternator current and the resistance of the charging cable while taking into account correction factors which take into account the different connections of the consuming devices between the alternator and the battery so that the calculated voltage drop and the optimum charging voltage for the battery can be used by the voltage regulator to set the voltage delivered to the battery.

摘要： A thermally dependent self-modifying voltage source (115) is constructed with a first reference circuit (301) having a control input (311), a primary output (117) dependent on the control input, and a thermally dependent secondary output (303). The thermally dependent self-modifying voltage source also includes a thermally dependent reference (309) with an output (307). The thermally dependent secondary output (303) of the first reference circuit (301) and output (307) of the thermally dependent reference (309) are coupled to inputs of an amplifier (305). The amplifier (305) has an output (313) coupled to the control input (311) of the first reference circuit (301), wherein the primary output (117) of the first reference circuit is dependent on the amplified difference between the thermally dependent secondary output (303) of the first reference circuit and the output (307) of the thermally dependent reference (309). Preferably, the primary output (117) is used in a voltage regulator (121) for use in alternator based battery charging system (100).

摘要： A reference voltage circuit for a voltage regulator control includes three parallel voltage dividers cross-coupled by oppositely poled diodes, one of the dividers having a negative voltage-temperature characteristic tied to the battery electrolyte temperature and another divider having a positive characteristic. With this arrangement the reference voltage remains constant below a first electrolyte temperature t1, decreases between t1 and a second, higher temperature t2, and decreases at a reduced rate above t2.

摘要： An alternating current (AC) generator of the type used in vehicular applications and driven by the vehicle engine has a stator winding and a field winding wherein the electrical resistance of the field winding varies as a function of temperature. An exciting current intermittently is allowed to flow through the field winding which induces a current in the stator winding. The output of the stator is rectified and used to charge the vehicle battery. The invention comprises inclusion of field winding current compensation apparatus which varies as a function of temperature to reduce undesired field winding current variations due to temperature which results in improvements of power output and stabilized generator driving torque.

摘要： A temperature compensation arrangement in or for battery charging equipment embodying a voltage regulator, the voltage regulator having a feedback arrangement in which a potential divider is provided for feeding back a fraction of the regulated voltage for regulating the charging current applied to a battery. The temperature compensation arrangement is provided with two shunt paths for shunting the respective parts of the potential divider, the impedance of the shunt paths being made variable in dependence upon the temperature of a part of the equipment so that the fraction of the regulated voltage fed back varies with temperature.

摘要： A temperature-controlled automobile voltage regulator comprising an emitter-coupled bistable circuit responsive to the alternator voltage for operating a current switch which so controls the current in the generator''s field winding that the alternator voltage bears a predetermined desired relationship to the ambient temperature of the regulator over a wide range of temperatures. A buffer stage, comprising an emitter-follower transistor amplifier, provides interstage coupling between the input and output stages of the bistable circuit. A temperature responsive circuit, comprising a transistor whose emitter-collector circuit is connected across part of the emitter resistance of the buffer stage, lowers the emitter resistance of the buffer stage as ambient temperature rises, thereby lowering the switching voltages of the bistable circuit. As a result the average current supplied by the current switch to the field winding of the alternator decreases, lowering the alternator''s output voltage as temperature rises, thereby to provide optimum battery charging.
