摘要：PURPOSE: An apparatus is provided to prevent reverse current which is inputted to a stack of a fuel cell of an electrical automobile by simply controlling a gate signal of an inverter which drives a motor. CONSTITUTION: An inverter(40) controls flow of current which provides a motor(50) and includes a plurality of switching transistors. A generator of a gate signal(30) generates and applies each switching signals to gates of the plurality of switching transistor of the inverter(40). A controller(10) generates a control signal for controlling the motor(50) when normal operating and then outputs the control signal to the generator of a gate signal(30). Furthermore, the controller(10) control the generator of a gate signal(30) to be disabled when the controller(10) receives a break signal from an electrical automobile. Therefore, the apparatus can prevent a reverse current which is generated from motor and is rotated so as to flow into a stack of a fuel cell of the electrical automobile.
