    Abstract: An electronically commutated fan system (100) includes an alternating-current-to-direct-current conversion unit (10), an inverter unit (20) and a control unit (30). The alternating-current-to-direct-current conversion unit (10) converts an alternating-current input power source (Viac) into a first direct-current power source (Vdcl). The inverter unit (20) is electrically connected between the alternating-current-to-direct-current conversion unit (10) and a fan (40). The inverter unit (20) converts the first direct-current power source (Vdcl) into an alternating-current output power source (Voac) and provides the alternating-current output power source (Voac) to the fan (40) to rotate. The control unit (30) is electrically connected to the alternating-current-to-direct-current conversion unit (10) and the inverter unit (20). The control unit (30) controls the alternating-current-to-direct-current conversion unit (10) and the inverter unit (20) to adjust a rotational speed of the fan (40). When the control unit (30) detects a power variation of the alternating-current input power source (Viac), the control unit (30) controls the rotational speed of the fan (40) to be maintained within a first error range (Rel).

    Abstract: The present invention provides an automotive electric power supply system that can prevent deterioration in electric power supply capacity due to discharging of a main electric power source, that can prevent large currents flowing from the main electric power source to a capacitor when a switch is closed, and that can achieve high-flux, high-output power generation.
    The main electric power source is connected to a lower-voltage side of a DC/DC converter by means of a first switch, and an electrical double-layer capacitor and a regulator circuit is connected to a higher-voltage side of the DC/DC converter. In addition, permanent magnets are disposed on a rotor so as to generate a magnetic field that is in a reverse direction to excitation by a field coil inside a claw-shaped magnetic pole portion of the rotor. A power supply control circuit controls opening and closing of the first switch so as to be in an open state when the engine is at rest, and so as to be set to a connected state after the regulator circuit is operated to make the alternator generate electric power to precharge the electrical double-layer capacitor after the engine is started.

    Abstract: Based on rotation information of a synchronous machine (5) detected by rotation information detection means (6), control means (7) cause a converter (2) to boost a charge voltage Vc of a capacitor (3) so as to be higher than an induced voltage Vm generated by the synchronous machine (5) at the time of shifting to a coasting operation, maintain the charge voltage (Vc) during the coasting operation, and perform a weak field control so that the induced voltage (Vm) generated by the synchronous machine (5) becomes lower than a DC voltage (Vdc) at the time of shifting from the coasting operation to a power running operation or to a regenerative operation.

    Abstract: A novel vehicle circuit system is supplied with electrical energy by a starter/generator which functions normally as a generator and can be used as a starter for starting. The starter/generator is connected to a 24 volt ring main system and to a 24 volt battery by pulse rectifiers, a 300 volt d.c. intermediate circuit, and a bidirectional transformer. Other consumers, as well as electric control devices, are supplied with voltages greater than 24 volts by the bidirectional push-pull transformer or the 300 volt d.c. intermediate circuit, if necessary via other transformers. This vehicle circuit system also contains a socket with a 220 volt 50 Hz power supply.
