“…For tuning of PI controllers there so many well-known optimisation techniques like Artificial Neural Network, Genetic Algorithm, Particle Sworn Optimization etc. are available for getting optimised controller parameters [27,28]. These optimising techniques have their own advantages and disadvantages and provide solution based on available mathematical model of the system.…”

In conventional DC link AC-AC converter system, uncontrolled front end converter has inherent problem of power quality. To overcome the problem associated with uncontrolled front end converter, multilevel front end converter will be good choice for high power applications. In the paper, unity power factor control system (UPC) for active front end (AFE) neutral point clamped (NPC) 3-level converter is presented. PI controllers are used in UPC and for tuning of PI controllers it is essentially required to know the different time constants with their gains exactly for evaluating the optimized controller parameters for steady operation of the NPC rectifier. In this paper a simplified and accurate method of online tuning of PI controllers in UPC is derived and implemented for three phase AFE NPC 3-level converter. Complete design procedure for the design of control system for AFE NPC 3-level is also presented in this paper. Based on developed model, simulations are carried in MATLAB/SIMULIK environment. Experimentation results confirm the simulation results.

SummaryMultilevel inverter is a practical power electronic design that has motivated a great deal of ever‐increasing interest. In this article, a new design of basic module‐based multilevel is proposed. The article conceptualized minimizing the number of power semiconductor devices, losses, and total blocking voltage and hence the cost. The proposed inverter structure consists of both a polarity generator and a level generator unit. To investigate the eminence of the proposed topology, an exhaustive comparative study with other existing topologies is presented. The proposed inverter can be utilized for both symmetrical and asymmetrical configurations. The extended cascaded structure of the proposed topology is discussed for generating a higher level of voltages and five algorithms for asymmetrical configuration are introduced to select input dc voltages. This article presents the operating principle, modulation strategy, total standing voltage calculation, cost function, and losses calculation. The efficacy of the proposed cascaded multilevel inverter has been substantiated experimentally. The proposed structure can be efficiently used in medium‐/high‐voltage applications like electrical drives as well as renewable energy resource‐based grid‐connected systems.
