摘要： A battery charger has a control circuit portion and a power circuit portion with common terminals to connect to a battery desired to be recharged, the power circuit includes a transformer and rectifier to deliver at least partially rectified A-C current to the battery, and an A-C power connection through which A-C power is supplied to the power circuit with the control circuit having a solid state switch to selectively connect the A-C power to the power circuit portion. The control circuit portion of the charger has a D-C disconnect feature which senses the interruption in the electrical circuit between the charger's terminals and the battery, said disconnect feature causing the operation of the A-C power switching device to disconnect the A-C power from the power circuit after the terminals have been disconnected. A further feature is an A-C interrupt feature which senses the disconnection or interruption of A-C power from the power circuit, latches the A-C power turn off control in its off condition, interrupts the voltage following and timing charge control and maintains it in readiness for resumption of the charging cycle, at the interrupted point in the cycle, after the A-C power has been restored.

摘要： A motor vehicle electrical system which is capable of supplying both 12 and 24 volt loads. A pair of 12 volt batteries are permanently connected in series and are charged in series under certain conditions of operation from a 24 volt charging system including an alternating current generator and a bridge rectifier. The output voltage of the 24 volt charging system is maintained substantially constant by a voltage regulator connected with the field of the generator which senses and responds to the output voltage of the bridge rectifier that is applied to the series connected batteries and other 24 volt loads. An auxiliary charging circuit is provided connected between one of the phase windings of the generator and the junction of the series connected batteries for, at times, supplying current to one of the batteries that supplies the 12 volt loads. This circuit includes a series connected silicon controlled rectifier and inductance. The controlled rectifier is gated into conduction whenever the voltage at the junction of the two batteries drops below a voltage corresponding substantially to one-half of the output voltage of the bridge rectifier that feeds the 24 volt loads.

摘要： Apparatus for transferring electrical power between a power supplying apparatus and power consuming apparatus and having a separable high frequency transformer with a primary permanently mounted to the power supply apparatus and a secondary mounted about the power consuming apparatus. A charging control circuit mounted on the consuming apparatus, e.g. a mobile vehicle includes means for detecting current and voltage delivered through the transformer, and also for monitoring storage batteries within the vehicle. The power supply apparatus includes a power supply circuit comprising a ferrite core transformer and capacitor forming a parallel resonant circuit. The primaries of the transformer are alternately driven by a driver about opposing polarities. The drivers are controlled by a voltage-controlled pulse-width modulator which provides a square wave input to the drivers to cause them to alternatively energize the ferrite core transformer. Power is transferred across the inductor to the resonant circuit as portions of a sine wave. The power supply circuit also includes an internal current sensing circuit to shut current build-up down when current in the resonant circuit becomes too high, and an external control loop which senses power demands of the charging control circuit delivered via an optical communications link within the separable transformer.

摘要： A full-charge indicator for battery chargers, includes a transistor which is in a conductive state as long as charging current to the battery is not less than a level which indicates that the battery did not reach full charge. When the battery reaches full charge, a voltage drop in a resistor in the charging current path is not sufficient to maintain the transistor in a conducting state, and therefore it is switched off. When this occurs an LED is turned on, to indicate a full charge state of the battery. A photocoupler together with a photocoupler transistor are included. When the transistor is off, the photocoupler activates the photocoupler transistor to shunt out a resistor, thereby reducing the charging current to the battery to a float charging current and prevent the battery from being overcharged and damaged.

摘要： Two SCR full-wave center-tapped rectifiers are connected in opposite polarity to battery charging terminals. The proper polarity rectifier is selected by a battery polarity sensing circuit that enables the firing of the SCRs of the proper rectifier. The sensing circuit has two transistors of opposite polarity. The transistor matching the polarity of the battery turns on and enables current to the proper SCR gates. The sensing circuit is controlled by an optical isolator that activates the circuit by shorting the polarized output of a diode bridge connected in the transistors's emitter circuit. This allows the optical isolator to control emitter current of either polarity.
