振幅補正不要な三相交流電源用連続的位相調整器 Continuous Phase Shifter without Amplitude Compensation for Three-Phase Electric Power Source
A new method to shift continuously a phase of the three-phase ac electric power source without any amplitude compensation has been proposed. A concrete design of the phase shifter for the three-phase power source is described in detail both on electrical connections and mechanical structures. The geometrical shape of a mechanical cam with which we can change continuously a value of phase-shifting is considered analytically and the mechanical link to vary a phase continuously by using the cam is presented schematically. It is shown that we can make easily a poly-phase ac electric power source with the same amplitude by using several phase-shifters proposed in this paper.
