ABSTRACT:
A microcomputer includes an actual DUTY value detection section that detects an actual DUTY value γx by measuring the ratio of time in which an output voltage of each phase becomes a power supply voltage in a cycle of a triangular wave. A dead time compensation computation section subtracts the actual DUTY value γx from a DUTY instruction value αx before correction, thereby computing a difference value Δx. Subsequently, the dead time compensation computation section adds the difference value Δx to dead time compensation amounts βxp, βxm, which have been used for correcting the DUTY instruction value αx, thereby determining new dead time compensation amounts βxp′ and βxm′. The dead time compensation amounts βxp, βxm stored in a memory are renewed with the new dead time compensation amounts βxp′, βxm′.
