Abstract
In a system, a triangular carrier wave is compared in magnitude with first and second two-phase modulated command signals. Based on a result of the comparison, on-off operations of the high- and low-side switching elements of two phases of a three-phase inverter corresponding to the first and second two-phase modulated command signals are performed while the high- and low-side switching elements of the remaining phase of the three-phase inverter is fixed to be on or off. A value of a current flowing through a first or second bus connected between a DC power source and the three-phase inverter is measured when a local peak of the triangular carrier signal occurs while none of the high-side switching elements of all the three-phases are on or none of the low-side switching elements of all the three-phases are on.
