| Abstract: | Multi-level inverter has been widely used in power electronics, and there is more and more study on its control strategy and thetopology. This thesis is concentrated on the topologies and working principle of diode clamped four-level inverter firstly, then introduces thevoltage shifting control strategy, lastly, MATLAB/simulink is used to simulate voltage shifting modulation strategy in four-level inverter. Somewaveforms for simulation are presented. |
