摘要： A portable power unit is provided. A desired waveform signal indicative of a desired waveform having a desired frequency is generated. Switching control of a variable control bridge circuit is performed based on the desired waveform signal to cause the variable control bridge circuit to generate an alternating current output. A waveform of the alternating current output is detected to generate an output waveform signal indicative of the detected waveform of the alternating current output. A power factor is detected by comparing the desired waveform signal and the output waveform signal to generate a power factor signal indicative of the detected power factor. Voltage of the alternating current output is controlled based on the power factor signal.

摘要： A cogeneration system that is operated in system connection is disconnected from the system and operated independently at a power failure of the system. A power generator 1 driven by an engine E is connected to a system 9. A water-cooling device 13 recovers exhaust heat of the engine E. When an operating switch 20 is switched, to its independent operation mode for an independent operation apart from the system 9, the upper limit of the target rotation speed Ntgt of an electronic governor 16 is increased over that at system connection operation, thereby the engine speed can be increased, and the maximum output point of the power generator 1 is increased for operation. When a power failure of the system 9 is detected by a power failure detecting unit 21, an operation mode judging unit 19 outputs a judgment result similar to that at the moment when the independent operation mode is instructed and increases the upper limit of the target engine speed Ntgt, and turns off a connection switch 7 to disconnect the system connection.

摘要： In a power supply apparatus having an engine operated generator, the operation of the power supply apparatus is improved in the efficiency in a light load region. The generator 1 is driven by the engine. The output of the generator 1 is converted into alternating power of a particular frequency by a rectifier circuit 2 and a converter 4 and is output to a load. A two-way DC-DC converter 5 supplies the power of a battery 6 to the converter 4. When a load current is equal to or less than a predetermined value, the power generated by the battery 6 is supplied to the load, and the power generated by the generator 1 is not used. If the power supply ability of the battery 6 is lowered, the power generated by the generator 1 is supplied to the load, and the battery 6 is charged.

摘要： A power unit is provided which is capable of controlling a rise in voltage applied to each of thyristors constituting a cycloconverter even when the output voltage of the power unit undergoes a temporary sharp rise due to characteristics of a load connected thereto. Positive and negative converters of the cycloconverter are connected to three-phase output windings of a three-phase generator and connected in an antiparallel manner to each other for generating a single-phase alternating current to be supplied via a pair of output lines to the load. A firing angle control device causes the positive and negative converters to be alternately switched to operate every half a repetition period of the single-phase alternating current, to thereby cause the cycloconverter to generate the single-phase alternating current. A bridge rectifier is connected between the pair of output lines. An electric energy-storing capacitor circuit is connected to the output of the bridge rectifier, for storing the rectified output therein.

摘要： A portable power unit has a magneto generator having three-phase output windings. A synchronizing signal is formed in synchronism with an output frequency of the magneto generator. A pair of variable control bridge circuits are connected to the three-phase output windings and connected in antiparallel connection to each other to form a cycloconverter for generating a single-phase alternating current having a desired frequency to be supplied to a load. A bridge drive circuit is responsive to the synchronizing signal from the synchronizing signal-forming circuit, for causing the pair of variable control bridge circuits to be alternately switched to operate every half a repetition period of the single-phase alternating current, to thereby cause the cycloconverter to generate the single-phase alternating current. An output voltage-detecting circuit detects an output voltage of the pair of variable control bridge circuits. An output voltage-adjusting circuit compares the output voltage detected by the output voltage-detecting circuit with a desired voltage to thereby control the bridge drive circuit in a manner such that the output voltage of the pair of variable control bridge circuits is maintained substantially at a fixed value.

摘要： A control system for an internal combustion engine having a pressurized gaseous fuel source, a control valve for regulating the amount of gaseous fuel supplied from the pressurized gaseous fuel source, and an intake passage in which the gaseous fuel, the amount of which has been regulated by the control valve, is mixed with intake air and supplied to the engine as an air-fuel mixture. An ECU of the control system controls the air-fuel ratio of the air-fuel mixture to be supplied to the engine by regulating the amount of the gaseous fuel through the control valve, and various sensors detect operating conditions of the engine. The ignition timing of the engine is calculated based on the detected operating conditions, and when the air-fuel ratio of the air-fuel mixture is in a predetermined lean limit region, the output of the engine is controlled by correcting the ignition timing.
