Design Projection Of Three-level SVPWM Inverter On DSP

Because of having the high and dynamic function of efficiency, pro-ducing less harmonic wave to electric motor, and suiting high-performance voltage large capacity, multilevel inverters are applied in high-voltage and high-power applications. This paper overviews the controlling technique and the device's development of the multilevel inverters, studies the development foreground of multilevel inverters.The thesis introduces work principle of two levels inverters in detail, studies the principle of the voltage vector modulating technique, analyzes the advantage of the voltage vector modulating calculation comparing with other means. The neutral-point balancing problem of the three-level neutral-point-clamped (NPC) inverter has received a large amount of attention in recent years. This paper mainly introducesa new way of balancing the neutral-point voltage. Multilevel inverters offer the advantage of effectively stacking the switching devices in series, thereby providing a higher dc-bus voltage than can be obtained by conventional techniques .At the same time, the harmonic content ofthe output voltage waveform is significantly reduced compared to con-ventionaltwo-level inverters .At last we simulate the SVPWM modulating means of three-level inverters by MATLAB, and prove the correction of modulating means.What is more, this paper introduces the TMS320F2407 DSP (TI), and completes the designation of the system hardware by the TMS320F2407 DSP.
