3-level inverter를 위한 새로운 Carrier-Based DPWM 기법
The Novel Carrier-Based DPWM Method for 3-level Inverter
초록
This paper deals with the novel DPWM(discontinuous PWM) for 3-level inverter. Although DPWM methods generate higher harmonics than SVPWM they are of special interest because of their lower switching losses. And in the high modulation region the harmonic characteristics of DPWM is superior to the that of CPWM. However when DPWM applies to the 3-level inverter there is the problem that the output state is varied suddenly in the low modulation region(
