Abstract
The AC converter converts a single-phase input AC voltage with a frequency f0 into a three-phase output AC voltage with a frequency f1 that is lower than f0. The AC converter includes a switching section with multiple switching elements and a switching control section that controls the conduction states of the respective switching elements. The switching control section supplies pulses that have been subjected to a pulse density modulation based on space vector modulation to the switching section, thereby getting the conversion into a three-phase output AC voltage done.
