The voltage quality issues shows the significant effect on the performance of radial secondary distribution feeder. This paper aims to enhance the voltage regulation of radial secondary distribution feeder system using 5-level TCHB inverter based dynamic voltage restorer. Series voltage drop is the major factor causes poor voltage regulation. A 5-level TCHB inverter based DVR is used to inject the same amount of voltage dropped by series impedance. The DVR injects voltage with proper magnitude, phase and frequency with the proposed single phase PLL based SRF control circuitry. This enhances the voltage regulation by maintaining the load voltage at its rated value. Both the simulation and hardware results shows the enhancement of voltage regulation with mitigation using DVR.dynamic voltage restorer (DVR), modulation index (MI), multi-level inverter (MLI), phase locked loop (PLL), pulse width modulation (PWM), total harmonic distortion (THD), transistor-clamped H-bridge (TCHB), voltage regulation (VR), voltage source converter (VSC)

“…To address the aforementioned issue and to fulfill the high-performance IPMSM application requirements (e.g., EVAs), numerous multilevel power converter structures are recognized: neutral-point clamped (NPC), flying capacitor (FC), cascade H-bridge (CHB), and modular multilevel (MM) [27][28][29]. Several researchers have investigated the multilevel power converter, thanks to its benefits: low voltage applied to each component, less dv/dt and low THD of the output voltage and current waveforms, and low switching loss using the redundancy of the switching states [30,31]. In recent years, the NPC and T-type are the most used multilevel power converter topologies in the industry [32][33][34].…”

This paper proposes a novel predictive strategy based on a model predictive control (MPC) for the interior permanent magnet synchronous motors (IPMSMs) driven by a three-level simplified neutral-point clamped inverter (3L-SNPC) for electric vehicle applications (EVAs). Based on the prediction of the future behavior of the controlled variables, a predefined multiobjective cost function incorporates the control objectives which are evaluated for every sampling period to generate the optimal switching state applied directly to the inverter without the modulation stage. The control objectives in this paper are tracking current capacity, neutral-point voltage balancing, common-mode voltage control, and switching frequency reduction. The principal concepts of the novel scheme are summarized as follows: first, the delay compensation based on the long horizon of prediction is adopted by a multilevel power converter structure. Second, based on the modified Lyapunov candidate function, both stability and recursive feasibility are ensured of the proposed predictive scheme. Third, the practicability of the real-time implementation is improved by the proposed “static voltage vector” (SVV) and “single state variation” (SSV) principles. Finally, the proposed concepts are implemented in the novel predictive control formulation as additional constraints without compromising the complexity and the good performances of the predictive controller. Therefore, only the switching states that guarantee the stability and the reduction of calculation burden criteria are considered in the evaluation of cost function. The proposed predictive scheme based on the “SVV” principle has demonstrated superior performance in simulation compared with the proposed scheme with the “SSV” principle. The computational burden and switching frequency rates are reduced by 35% and 56.22%, respectively.
