description The invention discloses a design method of a driving circuit, which comprises the following steps: selecting a triode MMBT5551 device, calculating that a current-limiting resistor R3 of a second-stage triode is 200K, a current-limiting resistor R1 and a current-limiting resistor R2 of a first-stage triode are 2K resistors, connecting 820P capacitors in parallel beside the resistors R1 and R2 after simulation debugging to increase the rising speed of the driving circuit, drawing a schematic diagram of the driving circuit, and calculating the driving circuit. A control level is input through the input end IN and reaches the base electrodes of the triode Q1 and the triode Q2 through the current-limiting resistor R1 and the current-limiting resistor R2. And drawing an actual PCB circuit board by using AD software to complete the circuit design of the drive board. In the design of the driving circuit, the acceleration capacitors C1 and C2 are connected in parallel beside the current-limiting resistors R1 and R2, s
