摘要： Engine starting performance is enhanced by a brushless motor having no rotor position detecting sensor. In the first place an engine is rotated forward and then is reversely rotated to overcome a high load region of the engine. Then, the engine is accelerated and rotated forward and started. In a light load region of the engine, the engine is immediately accelerated and normally rotated. It is judged whether the region of the engine is the high load region or light load region based on the rotation speed when the starting operation is started. After the starting operation is started, if the forward rotation speed reaches a first speed, and a second speed which is higher than the first speed is obtained even after predetermined time is elapsed, an immediate starting-judging section 36 outputs a detection signal to a starting/normal rotation control section 37.

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： The invention makes an output sharing of an engine and an electric motor proper so as to suitably drive a load. When a throttle opening degree variation amount ΔV is within a ΔV1, an engine E can drive a power generator G at a rated revolution speed. A switching circuit 28 is switched in such a manner as to charge a battery 27 by a generated power. When the opening degree variation amount ΔV becomes larger than the ΔV1, a power assist of operating the power generator G as the electric motor is set to be standby. When the opening degree variation amount ΔV is more than ΔV2 (>ΔV1), the power assist is started. In the power assist, an angle advance amount is increased. When acceleration is insufficient, it is possible to further increase a conduction angle in stages.

摘要： In an engine drive washing machine, a discharge switch 10 is provided in a jet gun 5. When the switch 10 is turned off, an engine 1 is stopped. When the switch 10 is turned on, the engine 1 is started up to drive a pump 2. When an outlet pressure of the pump 2 is not lower than a predetermined value, a water-discharge valve in the gun 5 is opened to cause the water to be discharged. When the switch 10 is not turned off for a long time, the engine 1 is stopped. When an operator takes up the gun 5 to start the operation, the engine 1 is started up. The engine-drive type of washing machine is provided with a battery 13 for a starter motor, and the battery 13 is charged by a generator function of a starter-motor generator 3 during the operation of the engine 1.

摘要： In a cycloconverter generator, AC power required by the load is detected and a desired speed of the engine is determined based on the required AC power, operation of an actuator is controlled such that the engine speed becomes equal to the desired engine speed, and the required AC power is generated by turning on switching elements (thyristors) such that a number of the phase signal within one period of frequency of the AC power, becomes equal to a number determined by the desired engine speed, thereby preventing undesirable increase in fuel consumption and noise by operating the engine at a speed corresponding to required AC power and enabling to generate stable AC power even when the engine speed changes abruptly.
