Aggregate Factors of Switchings and Integrated Voltage Harmonics of Three-Phase Multilevel Voltage Source Inverter with Nearest Vector Selecting Space Vector Control

摘要

The paper deals with the model of the nearest vector selecting space vector control (SVC) of any arbitrary MLVSI circuit with any arbitrary number of any equal feeding DC voltage levels. Using the LabViewsimulation results for instantaneous SVC, the aggregate factors of switchings and integrated voltage harmonics (ASIHF) dependences on phase voltage amplitude modulation index are obtained and compared with the corresponding results of the quarter-wave symmetric space vector PWM (SVPWM).
