PROBLEM TO BE SOLVED: To generate a gate signal to be supplied to a driver for driving a motor through ON/OFF control of a gate from a command signal of a type different from that of a command signal representing the temporal transition of input voltage to the motor.SOLUTION: A gate signal generation method includes the steps of:inputting a time command value having at least an absolute value representing timing of switching out of a code representing a switching direction of a gate between an OFF state and an ON state and the absolute value; generating a sawtooth wave signal whose level changes in one direction with the lapse of time; generating an absolute value signal representing an absolute value of the inputted time command value; comparing the sawtooth wave signal with the absolute value signal and generating a comparison result signal representing the comparison result; and generating a gate signal on the basis of the comparison result signal. |
