A method of stopping the operation of a power transistor of a vehicle in which the engine is extended, the method comprising: determining whether the engine speed is greater than or equal to the set maximum rotation speed when the vehicle is running (step 1); Continuously supplying fuel to the fuel cell (step 2), determining whether the injector is stopped when the engine speed is higher than the set maximum speed (step 3), and determining the engine speed when the injector is continuously operated. A step returning to step (step 4), a step of shutting off the supply of fuel upon stopping the injector (step 5), and an injection Determining whether the maximum rotational speed at the stop of the rotor is higher than the engine's maximum speed (step 6); and if the maximum rotational speed at the stop of the injector is lower than the rotational speed of the engine, returning to the step of determining whether the injector is stopped ( Step 7) and stopping the operation of the power transistor (step 8) when the maximum rotational speed at the time of stopping the injector is higher than the rotational speed of the engine.
