Firstly, the principle and the control structure of the electric driving system used in the circuit are studied. Then, the specific design of the circuit and the selection of components are described in detail. Besides, the topological structure and the specific circuit design of the power supply for the drive circuit are introduced. The experimental result shows that the linearity degree of the input voltage vs. the output current of the high power constant-cu
