Abstrakt

In order to solve the problem that the equivalent relationship between space vector pulse width modulation (SVPWM) and carrier-based pulse width modulation (CBPWM) in the field of single phase multi-level inverters is still unclear, this paper drew on the equivalent realization method of three-phase multi-level inverters. And the equivalent relationship between the two modulation strategies of SVPWM and CBPWM was studied in depth according to the characteristics of the multilevel single phase diode clamped inverter. By injecting the deduced DC component into the CBPWM modulated wave, the same modulation output sequence as SVPWM was obtained, and by further strictly derived, the DC component formula realizing the equivalent of any number segment SVPWM sequences and CBPWM was obtained under single phase NPC n-level inverters. Finally, the experiment verifies correctness of the equivalent relationship.
