摘要
Abstract
Neutral point clamped three-level inverter has become one of hotspots of studies and application in the field of high-voltage and high-power inverter,but its corresponding conventional space vector pulse width modulation (SVPWM) algorithm requires complex and time consuming calculations.The existing SVPWM simplified algorithms were analyzed and proposed an improved strategy.The improved algorithm carries out the judgments of large sectors,calculation of dwelling times and switching sequences,output waveform modified of the corresponding two-level PWM inverter by detecting the three-phase instantaneous value of output reference voltage.The entire modulation process takes only simple four arithmetic operations and its steps clear and easy to implement.Simulation results validate the simplified algorithm.关键词
