Definitions

• the present invention relates to a power generation control device applied to an automobile / motorcycle engine.
• a generator such as an automobile engine has a mouth consisting of a magnet connected to the crankshaft of the engine around a three-phase coil and three-phase AC power is generated by rotation of the mouth. .
• This generator is connected to the battery via a regulator for obtaining a rectifying action and a constant voltage. Since such a generator is attached to the crankshaft of the engine, it is a load on the engine in the power generation state. Therefore, in the case of operation requiring a high load such as acceleration or running on a hill, it is possible to stop the generator and use the energy corresponding to the load as travel energy effectively to substantially increase the engine output. Considered by the applicant.

• a sudden change in load can be achieved by first switching only one phase from ⁇ N to 0FF or vice versa without switching all three phases at once, and then switching the remaining phases. Can be avoided.
• Another preferred configuration example is characterized in that a zero point of the AC waveform from the generator is detected, a predetermined phase width is turned off from the zero point, and the phase width to be turned off is gradually lengthened or shortened. .
• the ONZOFF switching is gradually performed by the phase control of the AC generator. That is, by cutting the phase of a predetermined width from the zero point of the AC waveform of the three-phase generator and setting the output to 0, the output of the generator decreases, and the width of the phase to be cut is gradually lengthened and the whole is cut. By setting the phase to 0, rapid load fluctuation can be avoided.
