Title
Research on optimizing control of high-power dual-inverter drive system
Abstract
The superiority of Selective Harmonics Elimination Pulse Width Modulation (SHEPWM) control technique for dual inverter drive system is mainly studied. The SHEPWM mathematical model is established and its solving method is given. By analyzing the harmonic components of DC side capacitor in dual inverter, an optimizing control strategy based on SHEPWM is put forward for the structure of dual inverter drive system. Finally a computer simulation with obtained switching angles is made. The capacity current waveforms before and after optimizing control was compared, as well as the DC side harmonics while in the case of asymmetric load and symmetric load between two inverters. By analysis, the optimization strategy is verified and the optimizing goal by eliminating the harmonics below 103th in the output voltage is achieved.
