SVPWM Control of Cascaded H-Bridge Multilevel Inverters

Abstract:

To solve the problem of computational complexity in H bridge cascaded multilevel inverter (HBCMI) control, this paper proposes a simple space vector pulse width modulation control algorithm. Base on the topology configuration of HBCMI, the output voltage is deduced, which is the difference value between two-level inverter group output voltage formed by left bridge arms and by right bridge arms. The control complexity is independent of inverter voltage level and it is suitable to every voltage level. To verify the algorithms, different level cascaded H-bridge inverter drive systems were constructed and simulation results are present.
