碩士 === 逢甲大學 === 資訊電機工程碩士在職專班 === 94 === How to conquer the problem of shortage of automatic torque adjustment for electric motorcycles is the main purpose of this thesis. The structure of the electric motorcycle is explored in the first step. The single-quadrant chopper circuit and full-bridge dc-to-dc converter are applied to it for improving the performance through simulation and actual implement circuit. Based on the single-quadrant chopper circuit and differential amplifier, the step changed torque adjustment is constructed. With the help of Programmable Logic Controller (PLC), Human Machine Interface (HMI), and stepper motor, the stepless changed torque adjustment is achieved. Finally, the actual electric motorcycle with the proposed circuit is tested for different slop of the road to verify the result.
