High frequency performance of variable speed drives with reduced switching losses is merely suitable for precise industrial applications. LC filters are used between a five-phase two-level (FPTL) voltage source inverter (VSI) and a five-phase induction motor (FPIM) to minimize high-frequency losses in the motor, and thus improves the drive performance. It also reduces the high dv/dt at the motor terminals by supplying five-phase sinusoidal voltages. However, this impacts the closed-loop control of the FPIM drive due to sustained resonant frequency oscillations, which destabilizes the drive on certain operational points. Various continuous and discontinuous high-frequency space vector pulse width modulation (SVPWM) techniques are proposed in this paper with detailed analysis. An improved current ripple prediction method is also applied to dampen the resonant frequency and enhance the capabilities of the FPTL FPIM drive. This system is more capable of stable operation without using any auxiliary circuit or high-frequency sensor. Drive stability is tested and verified under different test conditions by simulation as well as experimental results.

This paper proposes a high temperature (HT) and radiation tolerant silicon carbide (SiC) technology that is comprised of integrated circuits and complementary power devices for use in power applications such as spacecraft motor drive modules for robotic science probes. This work evaluates the capability of SiC power semiconductor devices, in particular 4H-SiC DMOSFETs (double-implanted metal oxide semiconductor field effect transistors) and Schottky barrier diodes (SBD) for applications in >400°C harsh environment power electronics. Novel structures for the 4H-SiC DMOS and SBD are proposed and the temperature dependent characterization of relevant device parameters such as: channel resistance, device junction capacitances are performed through simulating device models. In this work, a complete proof-of-concept of HT non-inverting buck-boost (NIBB) DC-DC converter using the proposed MOS electronics is designed and fabricated, which is demonstrated to operate at ambient temperatures as high as 600°C. For verification of the proposed semiconductor modeling, a simulation study is performed in LTSpice on a NIBB converter that incorporates the developed SiC device models and converts 20V-80V input to 60V-100V output at an efficiency over 92% with rated power of 200W for stepper motor driver application.

In this paper, a power converter architecture is implemented for charging of electric vehicles (EVs), which is based on a cascaded multi-level converter with an integrated split-energy storage units. The power interface between each submodule and EV is connected to an isolated bidirectional DC-DC converter. A unit-template based model predictive control (MPC) is implemented to improve power quality and reliability of the distribution network while charging an EV battery. The MPC approach in this paper, consists of three steps: The first step is an optimization problem i.e., current-control in MPC, the second step is the design making step regarding weighting factor and the third is the fault detection and action control. Further, state of charge balancing is also achieved using MPC to charge/ discharge all split battery storage units at same rate. Finally, the control is verified by simulating the system in MATLAB/Simulink at different operating modes.

This paper aims to propose a methodology for rapidly evaluating Permanent Magnet Vernier Machine (VPMM) performance. This procedure, includes electromagnetic determination of machine flux density, back-EMF, current, and torque using Finite Element Algorithm (FEA). For demonstration, two VPMMs with different slot types have also been analyzed. It has been demonstrated that openslot VPMM has superior performance compared to unity flux modulation ratio split-pole VPMM. However, it is possible for split-pole VPMM to surpass open-slot VPMM either by optimizing the shape of Flux Modulating Poles (FMP) or by employing the concept of advanced VPMM, i.e., with non-unity flux modulation ratio.

This paper presents an improved H5 circuit based five-level quasi Z-source inverter for photovoltaic applications. The inverter circuit is formed by utilizing an improvised H5 circuit with a dual quasi Z-source that can produce a five-level stepped voltage waveform rather than a three-level voltage waveform. The developed modulation technique results in a trapezoidal common-mode voltage. An active filter was used to eliminate the leakage current and filter out the harmonics in order to feed the grid voltage. The converter also possesses the reactive power sourcing capability, which helps in supporting changing load conditions. The leakage current resulting from this converter is well within the stipulated IEEE standards.

The uncertainty and disturbance estimator (UDE) algorithm has been extensively developed and applied in uncertain systems for rejecting external disturbances and addressing uncertainties. Existing works in the literature mainly focus on reducing the total harmonic distortion (THD) of inverter's output voltage feeding nonlinear loads and thus enhancing the inverter's output voltage quality. However, such existing works lack a robustness guarantee in the presence of fundamental frequency fluctuations. In this paper, a multi-band-stop filter is designed based on the UDE algorithm to reduce the total harmonic distortion (THD) of inverter's output voltage and also to provide the robustness against fundamental frequency fluctuations by modifying the values of output impedance at relevant frequencies directly. The feasibility and robust performance of the proposed control method are justified with the experiments.

This paper presents the current-estimation and speed estimation for Permanent Magnet Synchronous Motor (PMSM) drive. The speed-sensorless is built using the Fictitious Quantity based Model Reference Adaptive System (Y-MRAS) for Vector Controlled PMSM drive. It is developed using reference-voltage, actual-currents in the reference-model, and actual-currents in the adjustable-model. The two-phase stationary reference frame currents are estimated using q-axes reference current and single current sensor information from A-phase. The current estimation technique is independent of machine parameters. The presented methods apply to all kinds of PMSM machines. These methods are mathematically modeled and simulated in MATLAB/SIMULINK platform and verified in Typhoon-HIL.

In this paper, a continuous input high step-up coupled inductor integrated quadratic boost converter is presented for photo voltaic applications. The integration of coupled inductor to the quadratic boost converter is acquiring better attention in contrast to a boost converter in terms of continuous input current and better voltage gain. Additionally, the continuous input current reinforces the life of the photo voltaic panel and discards the placement of a capacitor which makes the system bulky. The presented converter lifts the voltage gain by $N$ + 1 times of voltage gain of the quadratic boost converter by replacing the second inductor with coupled inductors and adding one extra capacitor and diode. The description, operating modes and steady-state analysis of the presented converter are discussed in detail. Finally, The validation of theoretical analysis is verified with simulation results.

In this paper, a new passive auxiliary circuit based boost converter is presented to provide soft-switching and zero input current ripple conditions. In this structure, the reverse recovery loss of the diode is minimized by turning off the diode under zero current switching (ZCS) condition. Besides, due to the effective performance of the auxiliary circuit, the switch turns off and on under zero voltage switching (ZVS) condition. Furthermore, the input current ripple has been minimized and this ripple is reduced nearly to zero. The performance of the proposed auxiliary circuit based boost converter has been investigated. The voltage gain, design procedure, efficiency analysis, and comparison results for the power converter are presented in the paper. Finally, simulation results are presented to validate the converter performance and its mathematical calculations.

In this paper, a hybrid integrator control for solar photovoltaic (PV) array and storage battery (SB) based microgrid with seamless mode transition capability is presented. In grid-connected mode (GM), the voltage source converter (VSC) operates in the current control mode using a hybrid integrator. In the event of grid outage, the system is made to operate in a standalone mode (SM) and the VSC control shifts to the voltage control mode. In addition, the load demand is met without any interruption and the surplus solar generation is used to charge the SB using a bidirectional DC-DC converter (BDC). Furthermore, the SB supplies the load demand even under the combination of grid outage and disrupted solar power generation. By the virtue of a boost converter control, the PV array delivers peak power in both modes. MATAB based simulation results corroborate the applicability of this new control.
