A new single modulating and single carrier‐based predictive current control technique for single‐phase quadruple boost multilevel inverter topology

Summary

A new floor function single carrier‐based modulated model predictive current control (F²‐SCM²PC²) technique has been proposed in this paper by considering traditional single‐phase quadruple boost switched capacitor‐based multilevel inverter (QB‐SCMLI) topology. Conventionally, the implementation process of single modulating and single carrier‐based pulse width modulation (PWM) techniques are very much complex and finite control set‐based model predictive control (FCS‐MPC) technique inherently operates with variable switching frequency (VSF) operation, which is not suitable for industrial applications. To alleviate the aforementioned issues, a new generalized closed‐loop F²‐SCM²PC² technique has been proposed. It consists of a simple PWM implementation process and can easily be integrated with a predictive algorithm, thereby providing a constant switching frequency (CSF) of operation. The particular single modulating and single carrier‐based PWM technique with floor function is also suitable for low and high switching frequency (LSF‐HSF) operations. The validation of floor function‐based PWM technique in open‐loop and closed‐loop F²‐SCM²PC² techniques has been effectively verified through experimentation on QB‐SCMLI topology with consideration of resistive–inductive load.
