“…Additionally, a neutral-point voltage deviation control algorithm [48][49][50] is applied to maintain voltage balance of splitting DC-link capacitors, by delivering the required incremental time interval ∆t with respect to the resulted instantaneous voltage error (V dc1 -V dc2 ) between the splitting DC-link capacitors. Finally, PWM switching pulses S 1−4 for controlling operation of SAPF are generated by a 25 kHz space vector PWM (SVPWM) current control algorithm [18,51,52].…”

“…The harmonic contents of the generated output voltage can be reduced greatly by increasing the number of output voltage levels. However, for SAPF applications, the multilevel inverters employed are mostly limited to three-level inverters [2,18,19], as the high number of switching states and severe voltage imbalance problems of multilevel inverters (five-level and above) pose a great challenge in controller design. In three-level neutral-point diode clamped (NPC) inverter, voltage across the two splitting DC-link capacitors must equally be maintained at half of the overall DC-link voltage [2,17,19] so that a balanced injection current can be generated for effective cancellation of harmonic currents.…”

Abstract:In this paper, a refined reference current generation algorithm based on instantaneous power (pq) theory is proposed, for operation of an indirect current controlled (ICC) three-level neutral-point diode clamped (NPC) inverter-based shunt active power filter (SAPF) under non-sinusoidal source voltage conditions. SAPF is recognized as one of the most effective solutions to current harmonics due to its flexibility in dealing with various power system conditions. As for its controller, pq theory has widely been applied to generate the desired reference current due to its simple implementation features. However, the conventional dependency on self-tuning filter (STF) in generating reference current has significantly limited mitigation performance of SAPF. Besides, the conventional STF-based pq theory algorithm is still considered to possess needless features which increase computational complexity. Furthermore, the conventional algorithm is mostly designed to suit operation of direct current controlled (DCC) SAPF which is incapable of handling switching ripples problems, thereby leading to inefficient mitigation performance. Therefore, three main improvements are performed which include replacement of STF with mathematical-based fundamental real power identifier, removal of redundant features, and generation of sinusoidal reference current. To validate effectiveness and feasibility of the proposed algorithm, simulation work in MATLAB-Simulink and laboratory test utilizing a TMS320F28335 digital signal processor (DSP) are performed. Both simulation and experimental findings demonstrate superiority of the proposed algorithm over the conventional algorithm.

“…It delivers the required magnitude I dc of instantaneous DC-link charging current i dc so that the similar amount of charging current can be drawn by the SAPF to regulate its switching losses. Finally, to manage switching operation of the SAPF, a 25 kHz three-level space vector PWM (SVPWM) current control algorithm [45][46][47] is applied. Basically, it generates PWM switching pulses S 1-4 based on the reference current signal i re f which is delivered by reference current generation algorithm, and ∆T signal.…”

A Self-Tuning Filter-Based Adaptive Linear Neuron Approach for Operation of Three-Level Inverter-Based Shunt Active Power Filters under Non-Ideal Source Voltage Conditions

This paper presents a self-tuning filter (STF)-based adaptive linear neuron (ADALINE) reference current generation algorithm to enhance the operation of a three-phase three-level neutral-point diode clamped (NPC) inverter-based shunt active power filter (SAPF) under non-ideal (unbalanced and/or distorted) source voltage conditions. SAPF is an effective and versatile mitigation tool for current harmonics. As for its controller, ADALINE-based reference current generation algorithmd have widely been applied and proven to work effectively under balanced and purely sinusoidal source voltage conditions. However, no work has been conducted to study its performance under non-ideal source voltage conditions. In this work, a STF-based fundamental voltage extraction algorithm is integrated with an ADALINE algorithm, serving as synchronizer algorithm to ensure in-phase operation of the generated reference current with the non-ideal source voltage. Hence, it completely eliminates any dependency on conventional synchronizer algorithms such as phase-locked loop (PLL) and zero-crossing detector (ZCD). Additionally, the proposed STF-based ADALINE algorithm implements the modified Widrow-Hoff (W-H) weight updating algorithm for fast generation of reference current. Both simulation and experimental works are performed to verify design concept and effectiveness of the proposed algorithm. Comparative study with another recently reported algorithm is performed to investigate the performance improvement achieved by SAPF while using the proposed algorithm.

“…Furthermore, voltage balancing of splitting DC-link capacitors is achieved via a neutral-point voltage deviation control algorithm [41][42][43] which ensures equal inflow and outflow of current at the neutral point Z, by adjusting the activation time of each switching device according to the instantaneous voltage across both splitting DC-link capacitors (V dc1 and V dc2 ). Finally, the switching control is accomplished through a 25 kHz Space Vector PWM (SVPWM) [15,16,41,44,45] switching algorithm.…”

DC-Link Capacitor Voltage Regulation for Three-Phase Three-Level Inverter-Based Shunt Active Power Filter with Inverted Error Deviation Control

et al. 2016

View full text Add to dashboard Cite

Abstract:A new control technique known as inverted error deviation (IED) control is incorporated into the main DC-link capacitor voltage regulation algorithm of a three-level neutral-point diode clamped (NPC) inverter-based shunt active power filter (SAPF) to enhance its performance in overall DC-link voltage regulation so as to improve its harmonics mitigation performances. In the SAPF controller, DC-link capacitor voltage regulation algorithms with either the proportional-integral (PI) or fuzzy logic control (FLC) technique have played a significant role in maintaining a constant DC-link voltage across the DC-link capacitors. However, both techniques are mostly operated based on a direct voltage error manipulation approach which is insufficient to address the severe DC-link voltage deviation that occurs during dynamic-state conditions. As a result, the conventional algorithms perform poorly with large overshoot, undershoot, and slow response time. Therefore, the IED control technique is proposed to precisely address the DC-link voltage deviation. To validate effectiveness and feasibility of the proposed algorithm, simulation work in MATLAB-Simulink and experimental implementation utilizing a TMS320F28335 Digital Signal Processor (DSP) are performed. Moreover, conventional algorithms with PI and FLC techniques are tested too for comparison purposes. Both simulation and experimental results are presented, confirming the improvement achieved by the proposed algorithm in terms of accuracy and dynamic response in comparison to the conventional algorithms.
