Abstract

with the development of high technology, inverter request higher capacity. However, the traditional two level inverter capacities of the power electronic devices have been difficult to achieve high power requirements. Therefore, the national science and technology workers continue to put forward a variety of excellent performance of new multilevel inverter topology. This paper introduces five-level neutral point clamped inverter topology structure, characteristic and working principle. The voltage shifted modulation technology in PWM IPD, POD and APOD three arrangements and principle are described in detail. Then a simulation study gave out three kinds of arrangement of current , phase voltage and line voltage waveform and spectrum diagram. The simulation shows the three harmonic injection methods in five-level inverter application feasibility and correctness.
