ようになっていた。2. Description of the Related Art As a conventional device for changing a star-shaped connection to a triangular connection, a conventional device has been used, such as Japanese Utility Model Publication No. 55-90148.
【０００３】上記例は、低速回転時は星形結線として誘
起電圧を大きくすることにより、高速時においては内部
抵抗を小さくして、大電流を得ることにしている。In the above example, a large amount of current is obtained by increasing the induced voltage as a star connection during low-speed rotation and decreasing the internal resistance at high speed.

電流が流れることを考慮していなかった。In the above-mentioned prior art, in the case of star-shaped connection, the induced voltage of each stator coil is a sine wave in the production of a generator, it is difficult for the phase to be correct, and a circulating current flows. I didn't consider it.
【０００５】この循環電流が大きくなると、出力電流は
低下し、かつステータコイルの発熱が大きくなり、絶縁
破壊が生じた。When this circulating current becomes large, the output current drops, and the heat generation of the stator coil also becomes large, causing dielectric breakdown.

A diode is connected to the (−) side of the rectifier circuit (B), and a semiconductor element capable of short-circuiting the (+) side and the (−) side of the rectifier circuit (B) is provided.

まる出力電流が得られる。誘起電圧が正弦波でなくと
も、あるいは位相が少しずれていてもまったく支障はな
い。In the stator coil, since the diode is incorporated so as to be full-wave rectified, the circulating current does not flow, and each stator coil induced voltage and the output current determined by the resistance are obtained. There is no problem even if the induced voltage is not a sine wave or if the phase is slightly shifted.
【００１０】つぎに、半導体素子をショートすると星形
結線と、同じ通電ができる。このため出力電圧は増加
し、低速回転でもバッテリ電圧より大きくなり、発電電
流が流れる。Next, when the semiconductor element is short-circuited, the same electric current as the star connection can be obtained. Therefore, the output voltage increases, becomes larger than the battery voltage even at low speed rotation, and the generated current flows.
