Abstract:
1. A power converting apparatus, comprising: three input terminals configured to respectively receive a phase voltage of three-phase AC; three output terminals; first and second DC power supply lines; a converter including a first switch device group including an inverter including a second switch device group including a carrier generating unit configured to generate a carrier having a waveform in which an absolute value of a slope is constant with respect to time, with a reference internally dividing an amplitude of said waveform into a first value and a second value, said first and second values being current conduction rates; a converter gate signal generating unit configured to perform commutation of said converter at a timing at which said carrier takes said reference; and an inverter gate signal generating unit configured to allow adoption of a zero voltage vector as a switching mode of said inverter in a period in which said carrier changes a first command value to a second command value,
