20110261597 | INVERTER TYPE ENGINE GENERATOR - Generator output specifications according to destination are satisfied by an alternator with a single output band and a generator output voltage is made automatically adjustable in accordance with a load. An engine generator | 10-27-2011 |
20110271927 | AUTOMATIC START/STOP DEVICE FOR ENGINE-DRIVEN POWER GENERATOR - Starting and stopping an engine is automatically controlled based on a load without using a relay. An inverter engine-driven power generator has an alternator, a rectifying circuit, a DC/DC converter, and an inverter circuit. A load detection circuit is connected to an output of the inverter circuit in parallel. A load detection line of the load detection circuit is connected to an output line of the inverter circuit in parallel via resistors. A power supply formed of a battery is connected to the load detection line. A decision circuit outputs a load detection signal when a current having a preset value or more flows through the load detection line. A drive/stop CPU starts the engine in response to the load detection. The resistors are set at a resistance value which does not influence a load to which a generator output is supplied. | 11-10-2011 |
20110273148 | OUTPUT CONTROL DEVICE FOR HYBRID ENGINE-DRIVEN POWER GENERATOR - A power generator has a battery and an alternator driven by an engine. The battery assists a power energy of the alternator. An inverter circuit is connected to an output of a rectifying circuit. A DC/DC converter boosts a voltage of the battery and inputs the boosted voltage into a constant power regulator. The constant power regulator boosts an input voltage and secures a certain power. An output voltage of the rectifying circuit is monitored by a monitoring means and an output voltage of the battery is monitored by a monitoring means. When the output voltage of the rectifying circuit is equal to or less than a rated voltage, an auxiliary power value corresponding to the remaining amount of the battery is set as a power target value of the constant power regulator. | 11-10-2011 |
