Driving Device with Energy Feedback for Permanent Magnetic Mechanism

In this paper, a driving device with energy feedback for permanent magnetic mechanism is proposed. Firstly, the tripping circuit and the closing circuit are given and the formulas in tripping process and closing process are derived. By experiment, we get the waveforms and they are similar with the simulation waveforms. Finally, we can get the conclusion that the driving device and the function of energy feedback are practical.
