Zusammenfassung: | To provide a power generation device which easily appropriately maintains an output voltage over a wide range from low velocity to high velocity.SOLUTION: In a permanent magnet type power generation device, a coil unit is formed by dividing a coil for each pole into at least two or more regions, switch parts SW1 to SW12 capable of short-circuiting a portion of the regions are connected to the coil unit, and a voltage regulation part 22 automatically regulates an output voltage of the generator by controlling short-circuiting and open-circuiting of the switch parts in accordance with an operation velocity Sv of the generator. The short-circuiting of only coil regions L1, L3, L5, ..., at an equal electric angle in the coil unit is controlled. An AC output voltage is prevented from being unbalanced, and disorder of phase balance of three phases is avoided. A winding number ratio of multiple coil regions is adjusted to widen a velocity range. A coil region that can be short-circuited is constituted of a thin wire.SELECTED DRAWING: Figure 2
【課題】低速から高速まで広い範囲に亘り、出力電圧を適切に維持することが容易な発電装置を提供すること。【解決手段】永久磁石式の発電装置において、1極あたりのコイルを少なくとも2つ以上の領域に分割することでコイルユニットを形成し、前記コイルユニットにその一部分の領域を短絡可能なスイッチ部SW1〜SW12を接続し、電圧調整部22が、発電機の運転速度Svに合わせて前記スイッチ部の短絡および開放を制御し、前記発電機の出力電圧を自動的に調整する。コイルユニットの中で電気角が同じコイル領域L1,L3,L5,・・・のみを短絡制御する。交流の出力電圧が不平衡になるのを防止すると共に、3相の位相バランスが崩れるのを避けることができる。複数のコイル領域の巻き数比を調整して速度範囲を広くする。短絡可能なコイル領域は細い電線で構成する。【選択図】図2 |
