Three-port converters are commonly used in solar photovoltaic (PV)-based applications catering stand-alone loads with energy storage. This article introduces a new partially isolated PV-battery-based three-port dc–dc converter (PBTPC) for the aforesaid application. The proposed converter has two input ports and one output port, which is isolated from the input ports using a high-frequency transformer. The two input ports are used to interface PV and battery, and the output port is regulated at 400 V. Compared with the existing solutions reported in the literature, the proposed converter has the advantages of reduced semiconductor device count, higher voltage gain, and better component sharing. The two inductors used in PBTPC are arranged such that both PV and battery ports are current-fed ports. Moreover, PBTPC eliminates the need for multiple high-frequency transformers and the requirement for additional converters for PV control. The operation of PBTPC under different modes is analyzed in detail, and the outcome is presented with equivalent circuit diagrams and waveforms. A 400 W prototype is built, and the performance of PBTPC is authenticated experimentally under load and insolation changes.

This article presents a novel interior permanent magnet synchronous motor (IPMSM) model with a new PI proportional-resonant controller for emulation applications with the goal to accurately mimic the behavior of the lower order harmonics in the motor caused by drive inverter faults. The proposed method utilizes recurrent neural networks to model the machine under study with the goal to alleviate the computational burden of the emulator and reduce the overall latency in the system. To validate the accuracy of the proposed model, a comparative analysis with a look-up-table-based model under varying loading conditions has been conducted. The empirical findings validate the efficacy of the IPMSM emulator in facilitating drive inverter fault testing and demonstrate its utility in mitigating the risk of inverter impairment that may result from the emulation of machine behavior under such faulty circumstances. The proposed emulator is a significant advancement in the field of drive inverter fault testing, allowing for more accurate and efficient simulation of machine currents under defective conditions. This research provides a viable resolution to emulate the behavior of the machine at the presence of drive inverter switching failure.

This article reports a new single-stage wireless inductive power transfer (IPT) topology, which accepts both ac and dc input for electric vehicle battery charging applications. Also, the proposed system has bidirectional power flow capability; hence, the V2G operation is feasible. On the grid side, an ac–ac matrix converter converts the line frequency ac directly into high-frequency ac, thereby eliminating short-lived bulky dc-link capacitor. Achieving a unity power factor with traditional IPT topology is challenging because the front–end converter always has a buck-derived configuration. In this article, a boost-derived topology with bidirectional power transfer capability is proposed, which can maintain a unity power factor at the grid. The proposed single converter has the following three distinct operating modes: first grid to vehicle, second solar to vehicle, or the dc–dc, and third vehicle to grid mode. The steady-state operation, converter dynamic modeling based on small-signal analysis, and closed-loop control are reported for all the operating modes. The soft-switching performances are analyzed for the ac–ac converter and battery-side converter switches. A 700-W laboratory prototype is built, and the experimental results are presented to verify the analysis and performance of the proposed single-stage universal IPT topology.

A solution to provide fault-tolerance features and reliability enhancement to the multilevel inverters for remote and emergency load applications is proposed in this work. The proposed configuration can tolerate single and multiswitch faults and provides capacitor balancing features without using any voltage sensor circuitry. The converter proposed is derived by introducing a redundant unit with a resistor-switch circuit to the basic T-type three-level inverter, adding the multiphase fault-tolerant feature and improving the converter's reliability. This work uses level-shifted pulse width modulation, which is implemented in FPGA in driving the hardware prototype. The experimental results of the converter in healthy and different switch fault cases are presented and discussed in detail to validate the converter's fault-tolerant ability. Further, reliability analysis, efficiency analysis, and comprehensive comparison with state-of-art converters are presented to emphasize converter merits in remote and emergency load applications.

This article presents a modified single-ended primary inductance converter based single-stage ac–dc converter designed specifically for low voltage electric vehicles (LVEVs) charger applications. The rectifier showcases in this article demonstrates a high-step down buck gain, making it ideal for charging low-voltage battery packs commonly found in LVEVs. By utilizing a bridgeless structure at the input side with simultaneously operated switches, the converter reduces control complexity and eliminates the need for input voltage polarity sensing, a requirement in conventional continuous inductor current mode converters. The converter's extended step-down gain is achieved through switched-inductor structures, enabling it to deliver the required battery charging profile for low-voltage battery packs. Operating the inductors in discontinuous inductor current mode not only facilitates intrinsic power factor correction capabilities at the grid side but also reduces the size of magnetic components. DICM operation also provides zero-current turn- on for switches and zero-current turn- off capability for high-frequency diodes, thereby minimizing losses associated with diode reverse-recovery transitions. During testing on a proof-of-concept testbench at a power level of 450 W, the converter demonstrated a peak efficiency of 94.2% at rated power. In addition, the total harmonic distortion in input current was measured at 3.4%, showcasing a unity power factor and good power quality (PQ) indices at the grid. These results highlight the effectiveness of the converter in maintaining proper battery charging profiles while ensuring high efficiency and PQ standards in LVEV charging applications.

High-cost, slightly high input-power, and poor power-quality at a supply-side are the main concerns in a traditional brushless direct current motor ceiling-fan (BLDCM-CF), which limits its utility. This article addresses retrofit solutions of problems in an existing BLDCM-CF to increase utility and user attraction to use it. In this, discontinuous-conduction mode (DCM)-operated, coupled-inductor-based (CIB) switched-inductor Ćuk-converter (SICC) with an inherent active power factor correction is used at front-end to simplify control and to enhance supply-side-power-quality (SSPQ). Unlike an existing Ćuk-converter, presented SICC offers a high step-down gain with an effective operation over a wide variation in output-voltage (15–48 V), which partially fulfills requirement of a high-frequency transformer (HFT). It reduces HFT-losses and converter-cost. CF-motor is rewound for a 48 V with reduced-gauge aluminum-winding, which offers low i2R losses, cost, and weight. Moreover, inverter losses are minimized with fundamental switching. These modifications in an existing BLDCM-CF considerably reduce input-power, overall-cost, and weight. SSPQs are improved (crest-factor: 1.49, current THD: 1.38%, and PF: 0.999) with low power-input (27.73 W). Finally, the performance and effectiveness of given BLDCM-CF are validated using a lab-prototype.

High-gain dc-dc converters are becoming popular in various applications such as uninterruptible power supplies, grid integration, electric vehicles, etc. Analysis of the voltage gain, stability, and sensitivity factors of the high-gain dc-dc converters is essential in comparison with conventional dc-dc converters, primarily due to the increased number of passive components. In order to analyze these factors, different small-signal models are well-established for conventional dc-dc converters. However, these models do not consider all the effects of circuit parasitics. This article presents a detailed small-signal modeling of high-gain nonisolated switched inductor (NISI) and conventional boost converter topologies, taking into account all the effects of circuit parasitics. Further, the effect of circuit parasitics on the small-signal control-to-output transfer function and voltage gain of the high-gain NISI topology is highlighted. Later, simulation studies are carried-out on the high-gain NISI and conventional boost dc-dc converters, and the results are presented. Finally, the prototypes of the converters are fabricated, and experimental studies are carried-out to ascertain the results obtained from simulations. The measured maximum efficiency of the high-gain NISI converter is 95% at a power rating of 600 W.
