In this paper, a new 13-level inverter based on switched-capacitor is discussed. The design is appropriate for inexhaustible energy or green energy applications that need an input voltage source of low magnitude. With the use of switched capacitors, this device is capable of increasing the voltage by a factor of six. It doesn’t need complicated circuits or closed-loop controllers to make sure that the capacitors are balanced, and there are no control algorithms. The analysis of capacitance and the best value for capacitors are talked about. A good comparison is made between the proposed structure and the literature that already exists to see how well the inverter works. The results from the Matlab/Simulink application to find out the change in frequency, dynamic changes in load, changes in modulation index, and voltage across capacitors are provided to demonstrate that the suggested topology functions correctly and is risk-free. A more extensive version of this article is now being written, and once it is completed, it will be submitted to the journal along with the experiments.

Switched-capacitor (SC) based multilevel inverters (MLIs) have attained more attention owing to their ability to voltage boosting and self-balancing nature of SCs. However, these topologies suffer due to high current spikes resulting from the parallel connection of SCs with dc source. This article presents a five-level (5L) SC-based inverter to solve this problem while conserving the beneficial features of SCs. The proposed topology has a dedicated circuit comprising of one inductor and two power switches for ensuring a soft charging of the SC. The operation of the proposed topology is detailed. To attest the advantages of the proposed 5L topology, it has been thoroughly compared with other existing SC-MLIs topologies. The proposed topology is verified under both the steady and dynamic loading conditions, and the results are presented.

A charger topology using a single stage and transformer-less design employing bridgeless semi quadratic voltage gain with high power factor (HPF) AC-DC converter, is demonstrated in this paper for the charging system of light electric vehicles (LEVs). In order to achieve transformer-less structure and wide voltage gain (particularly step-down gain) between high AC input and low DC output (LEVs battery packs), an integrated structure comprising of a bridgeless SEPIC (single ended primary inductor converter) and a buck converter, is effectively utilized to achieve desired charging characteristics at the battery end and maintaining high power factor at AC end of the charger. The bridgeless along with the transformer less structure, together helps in reducing the size, and the cost of the charger and to improve its overall efficiency. Unlike existing SEPIC and Cuk HPF AC-DC converter based battery chargers, the presented charging system ensures continuous current characteristic both at AC side and battery end, and also has the freedom of operating in the discontinuous inductor current mode (DICM) operation. The continuous current characteristic considerably reduces the size of filters and minimizes associated losses, whereas the DICM operation enables control simplicity. Further, the DICM operation optimizes the volume of magnetics and ensures zero current switching of semiconductor devices. Lastly, the design, operating modes, and performance of the charging circuitry are verified through simulation and corresponding results are discussed here for performance verification.

Brushless DC motors, unlike normal DC motors, are supplied by a dc voltage supply and commuted electrically rather than using brushes. Electric cars, servo motors, linear motors, actuators, and other applications employ BLDC motors. The BLDC motor’s speed regulation is critical for completing the work at the required rate. We used code composer studio (CCS) software with INSTASPIN BLDC technology for this research work. We use cc studio software to analyze the motor properties and interface it with a GUI called INSTASPIN-MOTION MOTORWARE software. INSTASPIN BLDC is a method of control. It allows us to recognize, tune, and control any three-phase variable-speed motor. To drive the sensor and sensorless Insta Spin, we used a three-phase BLDC motor with DRVS301 and piccolo F28069M control card. The BLDC motor has dynamic performance and a low minimum operating speed in four modes. We enabled four blocks, namely Identify, Control, Plan, and Move, and analyzed the motor’s performance characteristics using the appropriate programs in the code composer studio. We used both open and closed-loop models to control the motor’s speed and analyze its performance characteristics.

In a home, off-board chargers are required to charge low voltage powered electric vehicles (LEVs) as well as high voltage powered electric vehicles (HEVs). Keeping this in view, this work presents the design and control of a single-stage bidirectional electric vehicle (EV) charger with a wide output voltage range from 72 V to 240 V. Moreover, the presented bidirectional EV charger facilitates the user to utilize the vehicle battery to supply the home loads, i.e. vehicle-to-home operation during the unavailability of grid power. A bidirectional bridgeless Cuk converter with a switched inductor is designed and analyzed for this EV charger. The main advantages of this bidirectional EV charger are regulated battery current and enhanced grid side performance with reduced component count during the bidirectional operation. The steady-state and dynamic performances of the designed battery charger are investigated under distinct operating conditions during EV charging and vehicle-to-home operation. At last, the efficacy of the battery EV charger is tested to comply with IEC 61000-3-2 standard for power quality and bidirectional operation with NEMA PE-5 standard towards battery current.

This paper proposes a Gallium Nitride high-electron mobility transistor (GaN HEMT) based three-port DC-DC converter for Level-1 and Level-2 electric vehicle charging. The three-port converter (TPC) is based on an isolated bidirectional Dual Active Bridge (IBDC-DAB) configuration for battery charging applications. The proposed DAB based TPC uses fewer components as compared to separate charger systems. The phase-shift control method is implemented to control the output power of the IBDC-DAB based converter with two charging output ports. The highest efficiency of 98.86% is achieved with the proposed converter at a phase-shift of 0.3889. The output ports 2 and 3 are designed for Level-1 and Level-2 EVB charging. Maximum power of approximately 2 kW for Level-1 and 12 kW for Level-2 is achieved for output Port 2 and 3 at an overall efficiency of 97%. The performance metrics of the IBDCDAB-based TPC have been analyzed and simulation is performed using LTspice XVII software. The results are presented for validation.

Current Transformer (CT) is the prime sensing device in power system for protection applications. Certain parameters of external circuit and CT itself may influence the operation of a protective schemes. During high fault current, its operating characteristic may disrupt and it creates nuisance operation of protective devices. Execution of CT in power system may affected by mismatch in CT ratio, CT saturation, error in measurement, fault inception angle (FIA), greater relay burden, remnant flux and several adverse effects in power system. Thus, it is a necessity to evaluate the performance of CT during such anomalous operating situations and its impact on the relaying schemes. Some special effects on current signals are generated using PSCAD software under different CT saturation conditions and system parameter variations. Time to enter the nonlinear region of operational protective CTs is additionally important and its refinements are also a major issue. This article covers the impact of variation in internal and external constraints of a system on saturation of CT during protection of the power system network. It has been observed that the behavior of CT changes from case to case due to linear and nonlinear operation during the different fault and fault inception angle.

A new multilevel converter configuration is introduced in this paper to feed the large-scale solar power in a three-phase grid. It is connected to the grid of 11 kV for a 1 MW medium power application. It utilizes twelve switches with symmetric progression to have nine levels in phase voltage and seventeen levels in line voltage. It has two units i.e. main power unit (MPU) and extension power units (EPU), which handle the solar power in a modular manner. Various states and operating modes are detailed to showcase the perfect operation of each level. This configuration is extendable to feed more power in a modular manner. Firstly, the converter operation is discussed, and later the converter is connected to the grid with a threephase closed-loop controller. The modeling and simulation are presented to test the system in an intermittent solar environment. A switching strategy with selective harmonics elimination (SHE) is employed to feed the power at fundamental frequency switching. This new solar converter feeds power in steady-state and dynamic conditions. The large-scale power is extendable with the extension of power units or a cascaded converter arrangement. Finally, a new solar converter is tested in Simulink to showcase the superiority of converter dynamics and control at the megawatt level for efficient grid-tied operation.
