Design and Simulation of Fault Tolerant 3- Ф Multilevel Inverter Topologies with Reduced Components: A Review

Abstract

Three-phase multiphase inverters are widely used in power distribution, motor, photovoltaic systems and other industries. In this article, STM32F407 will be used to control the multistage inverter. Compared with the digital signal processor F28335 (DSP), STM32F407 can be expanded to 56 ePWM and arithmetic operations. Thinking in other context, the number of ePWMs and the computational logic capacity of the DSP are inadequate. Also, the STM32F407 is cheaper than the DSP while retaining inverter features. Therefore, this new concept aims to pave the way for many applications and business opportunities. To prove this, the test results of STM32F407 control and DSP control card were compared.
