摘要： In a cogeneration system having a power plant comprising a generator connected to an AC power feed line between a power network and an electrical load and an internal combustion engine for driving the generator and for supplying its exhaust heat to a thermal load, the power supply from the generator to the power network is interrupted by turning off a switch installed in the feed line when an outage of the power network is detected, and a battery for storing DC power is connected to an inverter circuit to invert the DC power to AC power, such that the inverted AC power of the battery and the output of the generator are supplied to the electrical load, thereby enabling to respond to a power network outage for preventing reverse flow of the power output by the cogeneration system into the power network and supplying as much electric power as possible to the electrical load.

摘要： This invention realizes control without using a current-detecting element to prevent over current from flowing into a switching element of a switching converter in response to an input primary voltage from a small-capacity DC power source. The switching converter includes an FET 30 that turns the input primary voltage from the DC power source 1 on and off, and a choke coil 31 that is charged or discharged according to turning on/off of this FET 30. A driver 13 drives the FET so that an output voltage detected by an output voltage detector 9 is converged to a target voltage. A means for calculating a current I that flows into the FET 30 based on a duty ratio of the input primary voltage and the FET 30 and the inductance of the choke coil 31. The driver 13 drives the FET 30 at a duty ratio set so as to prevent the estimated current value I from exceeding a permissible current value or stops driving when the estimated current value I is equal to or more than the permissible current value.

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. A voltage-detecting circuit detects a voltage of the three-phase alternating current. An effective voltage value-calculating circuit calculates an effective value of the voltage of the alternating current. A reference sinusoidal waveform-forming circuit generates a voltage of a reference waveform for controlling the single-phase alternating current. A reference effective voltage value-generating circuit generates a reference effective voltage for controlling the single-phase alternating current. A firing angle control device controls the pair of variable control bridge circuits such that the pair of variable control bridge circuits alternately switch to operate every half a repetition period of the single-phase alternating current, so as to make the effective value of the voltage of the single-phase alternating current closer to a value of the reference effective voltage, and at the same time, make the voltage of the single-phase alternating current closer to the voltage having the reference waveform.
