The stator winding comprises a high-voltage cable with solid insulation. A rotor has a thermally based rotor current limit intersecting with a thermally based stator current limit in a capability graph at a power factor considerably below the rated power factor or has the thermally based rotor current limit above the thermally based stator current limit. In the capability graph. Means are provided for limiting the currents in order to avoid thermal damage. In a method for power and/or voltage control of such a synchronous machine, the machine operates with the stator current exceeding the thermally based stator current limit for a certain time period less than the maxim an permissible time limit, whereafter the overload is reduced by reduction of either the active power or the field current or a combination of both.

摘要： A method is for protecting a DC generator against overvoltage in the event of a loss of load. A voltage limit value is defined and, when starting the current generator, one or a few small current pulses are generated during an initial phase. The voltage is measured across the output of the current generator during the initial phase and the voltages measured across the output of the current generator are compared with the voltage limit value. There is a changeover to normal operation only if all the voltages across the output of the current generator measured during the initial phase are below the voltage limit value. The current generation is interrupted and a loss of load is indicated if any one of the voltages across the output of the current generator measured during the initial phase exceeds the voltage limit value.

摘要： A voltage regulator for an a.c. generator produces a power generation ratio signal having a duty ratio corresponding to the current supply to the field winding of the a.c. generator. This power generation ratio signal is applied to an external apparatus through a signal wire. The duty ratio of the power generation ratio signal is more than 10% when the a.c. generator is normal. When abnormality is detected, the power generation ratio signal is partly masked by an abnormality detection signal so that the duty ratio of the power generation signal is reduced to be less than 10% and this change may be detected by the external apparatus. Alternatively, the power generation ratio signal may be transmitted only intermittently when the abnormality is detected.

摘要： The invention relates to an apparatus for regulating the exciter current for a rotary-current generator. It has a voltage source, a rectifier, three phase windings, an evaluation unit, and a voltage regulator. The evaluation unit has three input terminals, and each of these input terminals is connected to one of the phase windings. The evaluation unit is intended for evaluating the phase voltages derived from the three phase windings, in order to detect error functions of the rectifier and/or of the phase windings. If such unauthorized work states are detected, then via the voltage regulator, the exciter current flowing through the exciter winding is reduced.

摘要： A rectifying section 2, and a DCDC converter 3 which lowers an input DC voltage and then outputs the voltage are disposed between an AC generator 1 and a load 4. When the output voltage Vt of the AC generator 1 is gradually lowered with starting from E0, the output power P is increased, and is maximum at Vt=V12. When the output voltage Vt is further lowered, the output power P is reduced. As an operating point at which the same output power P is obtained, there are a point of Vt=V11, and that of Vt=V13. The operation of the DCDC converter 3 is controlled so as to operate at the point of Vt=V13 where the output current I is lower.

摘要： An output stage of a conventional Frequency-on-Demand electronic voltage regulator, such as a voltage regulator of the type described in U.S. Pat. No. 5,642,033, is reconfigured as a bi-stable multivibrator, or flip-flop. An oscillator provides a reset pulse of pre-defined pulse width and pulse period to initiate an “on” period of the output stage; a conventional error amplifier synchronously switches the output stage “off” when a system voltage reaches a preset value. Voltage regulation by a constant-frequency, pulse-width-modulated, output signal is thus realized at reduced cost and complexity. Total capacitance between the gate-source terminals of a preferred MOS power output transistor serves to slow both negative- and positive-going output control signal transitions, introducing a minimum of electrical noise into the vehicle's electrical system.
