| 20120074912 | INVERTER GENERATOR - A control circuit (microcomputer) is provided in each of two inverter portions. Magnitude of a target waveform signal corresponding to a voltage to be output by each of the inverter portions is varied according to an operation state. The number of revolution of the engine is adjusted according to the larger one of the effective powers output from the two inverter portions. To cope with a temporary output shortage from the AC generator, the output voltage is temporarily lowered and then the output voltage is restored after waiting for the number of revolution of the engine increases. | 03-29-2012 |
