Abstract: A first primary winding N11 of a transformer 1 is connected with a commercial power source 30 via a transistor Q1, and a second primary winding N22 of the transformer 1 is connected with a backup battery 31 via a transistor Q2. An electric power on the second primary winding N12 is output for a controlling apparatus. When a voltage of the commercial power source 30 is larger than a predetermined value, a backup stopping circuit 10 turns off a LED 9 and stops the transistor Q2. The second primary winding N22 is connected with input terminals 14, 15 as a power source for charging a battery 31. While the transistor Q2 is stopped, an electric power for the battery is output from the second primary winding N22. Since the LED 9 turns on at the time of electric power breakdown, the electric power for the battery is stopped.

Abstract: A fault on the generator can be detected with the use of a simple arrangement. The output of the generator 12 which has multi-phase winding and is driven by an engine 11 is rectified and then converted by an inverter 133 into an alternating current at the frequency of a system before interconnected to the source of the system. After the engine 11 is started, the direct current voltage Vdc is monitored with a first fault monitor 40. When the direct current voltage Vdc rises up to a predetermined level, a connector relay 135 is closed. As the output of the inverter 133 is increased, the interconnection with the system source is enabled. After the interconnection, the direct current voltage and the output of the inverter are monitored with a second fault monitor 43. If the direct current voltage drops down to below the predetermined level before the output of the inverter reaches a rated level, the canceling and re-interconnection is repeated.

Abstract: A generator apparatus such as in a cogeneration system has a controlling power supply energized with its generator output with giving no adverse effect on the waveform of its output. An inverter 13 is provided for converting an alternating current output of the engine generator 10 into a direct current and returning back by the action of its inverter circuit 133 to an alternating current of a predetermined frequency which is then connected to a power supply system 14. While the engine 11 remains not actuated, a power received from a joint between the inverter 13 and the power supply system 14 is rectified by a rectifier 141 and transferred to the controlling power supply 140. When the engine 11 is started, the power at the input of the inverter circuit 133 is transmitted to the controlling power supply 140.
