    Unlike the resistance method, the voltage method involves changing the driving voltage during the control phase to control voltage and current overshoot. There are approximately two methods to change the driving voltage. One is to achieve the change by dividing the driving voltage through a resistor, and the other is to change the output signal in the control chip (DSPFPGA), and then convert it in...
