以穩定車用發電機輸出電壓為目的之主動式無段變速系統

本文之目的是藉由研究主動式CVT系統，並將此主動式CVT系統應用於控制車用發電機的轉速，使轉速達到穩定，以達成發電機輸出電力品質的穩定。 CVT無段變速系統由於其原理簡易，加上其變速特性平穩，在車輛變速系統應用相當廣泛。文中首先論述CVT系統之基本原理，個別分析其各部份組件的受力情形及平衡狀態，並建立其數學模型；接著分析其總受力平衡狀態，並組合出最後之受力總關係式。接著以感應電動機之電路模型，推出感應發電機之電路模型及數學關係式。之後參考目前市售速克達機車用之CVT變速系統尺寸，建立模擬主動式CVT系統之電腦模型，並找出其控制方式及控制關係數據。最後加入感應發電機之電腦模型，模擬主動式CVT系統之運作，並對其作控制。論文最終模擬結果發現，此主動式CVT能對轉速的控制和穩定發電機輸出能達到一定之效果。

In the recent years, the electronic controls for vehicles have been becoming a trend to the motor makers in competition of the world. In addition to various of new electronic devices introduced into the vehicles, the demands for power quality are also higher than before. However, for dealing with the cruising conditions, the engine speed always changes largely, so that variation of generation voltage is sharp. In convention, electronic constant voltage regulators (ECVR) are used for serving above problem, but there are several drawbacks existing. In order to completely improve the drawbacks of ECVR and make the drive of alternator in nearly constant speed, a design of ACVT (active continuous variable transmission) for vehicle generation is proposed in this paper. Make use of ACVT, the driven velocity of alternator transmitted from engine can be smoothened in constant, then the voltage of supply power are maintained in stability. The effectiveness and validity of this proposal are confirmed by a simulation study.
