Aiming at the problem of MOSFET turning - off spike voltage, the minimum gate resistance value which fits for the normal working of speed controller MOSFET is calculated by analyzing the relationship between parameters of the MOS- FET driving circuit. Simulation and experiment show that the problem of turning - off spike voltage can be solved by adjusting the gate resistance value, so as to ensure the reliable operation of high speed frequency - speed varied controller of battery forklift.
