摘要： 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.

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： To provide a DC-DC converter capable of suppressing switching loss with a simple structure, and capable of enhancing converting efficiency. An LC resonant circuit 3 is inserted on a secondary side of a transformer 1. If switching means 2 is turned ON or OFF by driving means 4, output can be obtained on the secondary side through the transformer 1. A resonant current frequency detecting means comprises a current detecting current transformer 5 and a frequency detecting unit 6. The resonant current frequency detecting means detects resonant current frequency caused by operation of the LC resonant circuit 3. This frequency is fed back to the driving means. As a result, the driving means 4 turns the switching means 2 ON or OFF at a frequency corresponding to the resonant frequency of the LC resonant circuit 3.

摘要： An N-channel MOS transistor is used to configure a DC—DC converter having good characteristics without providing a particular voltage circuit which outputs a voltage higher than an input voltage. An N-channel MOS transistor 11 and a choke coil 12 are connected in series between a negative side of a direct-current power supply and a negative side of the output capacitor 8. A PWM circuit 14 applies pulse signals to a gate of the MOS transistor 11 based on the input voltage divided by the capacitors 9 and 10. The pulse signal of the PWM circuit 14 is formed by the voltage corresponding to the output voltage of the output capacitor 8, and the pulse signal is inputted to the gate of the N-channel MOS transistor 11 through a photocoupler 16.

摘要： An inverter 3 is controlled by feeding back an output voltage waveform for stabilizing the output and circuitry simplification. The output waveform of an inverter 3 is supplied to a CPU 5 to generate a correction of the reference sine waveform signal RS which is then used for producing a desired form of PWM signal. The output waveform is A/D converted by a converter 18 which comprises two modules 19 and 20 before transferred to a processor 50. The output waveform is received by two channels of each of the modules 19 and 20. As the input channels are sampled in a sequence, their waveforms are A/D converted at intervals of a time in each sampling period and can thus be improved in the resolution of A/D conversion. Since the modules 19 and 20 are operated at different timings lagged slightly from each other, the resolution can be increased.

摘要： A power unit is provided which can perform stable feedback control by reducing a feedback gain, and sufficiently cope with fluctuations in the output voltage occurring according to fluctuations in the input voltage caused by fluctuations in the rotational speed of an engine. A pair of variable control bridge circuits are connected to three-phase output windings of a three-phase generator driven by the engine, and connected in an antiparallel manner to each other to form a cycloconverter for generating a single-phase alternating current to be supplied to a load. An effective voltage value-detecting circuits detects an effective value of a voltage of the alternating current. A reference effective voltage value-generating circuit generates a reference effective voltage for controlling the single-phase alternating current. A target wave-forming circuit forms a target wave for making the effective value of the voltage closer to a value of the reference effective voltage. A firing angle control device performs switching control of the variable control bridge circuits, based on the target wave, such that the variable control bridge circuits are alternately switched to operate every half a repetition period of the alternating current. A rotational fluctuation-detecting circuit detects fluctuations in a rotational speed of the engine in a rotation cycle thereof. A gain-adjusting circuit generates a reverse characteristic signal having a characteristic reverse to a characteristic of the fluctuations in the rotational speed of the engine. A comparator corrects amplitude of the target wave based on the reverse characteristic signal.

摘要： Two generation systems 3, 8 each including inverter 8 are switched over between series connection and parallel connection by switching section 5. Reference waveform signals are mutually communicated between the two generation systems through communication lines 6. When a phase difference between these two reference waveform signals is within a predetermined range, the inverters are driven to generate an output alternating current. One of the conduction angles of thyristors 3a, 3a in two converters 3, 3 which is larger than the other is inputted to a deviation detector 42. Based on a deviation of the conduction angle inputted from a target conduction angle, an updated target rotational speed is set in a calculator 44. A throttle controller 48 controls a throttle opening angle so that an actual rotational speed converges into the target rotational speed. A ground fault is judged based on a potential difference across one node point in a first arm, connected to the earth and the other node point in a second arm of a resistance bridge provided across a pair of output terminals of either one of the inverters.
