    Design and Development of Integrated-Isolated DC-DC Converter

  • A single-phase voltage source converter and three-phase phase-modular AC-DC converter have the problem of high DC-link capacitor requirement. In this work, a novel 1 kW SiC-MOSFETs based hybrid isolated DC-DC converter was developed, with reduced capacitor requirement and delivering the desired output power to load without using any extra switch. Additionally, the converter exhibits the advantage of zero-voltage switching (ZVS) within a specific range. The developed control technique for a hybrid isolated DC-DC converter was verified by using a specially designed low-noise immunity current and voltage sensor board integrated with Texas Instruments microcontroller (TMS320f28379D).
  • SiC-based full-bridge-based hybrid DC-DC converter was developed to perform active power buffering in multilevel converters, which have applications in ultra-fast EV charging stations, large-scale solar PV systems, railway traction systems and split-battery energy storage systems. With minimal switch requirement and folder/ unfolder concept, the derived output power was maintained with a low DC-link capacitor requirement.

    Control and Modulation Strategies for buck-based Electronic Capacitor

  • In this project, a novel control method for 500W SiC MOSFET based EC converter was proposed, which entitles the design of a faster decoupling control, while ensuring the system stability and efficiency during dynamic periods. This control facilitates the rapid adjustment of decoupling capacitor voltage with a change in output power. Although the developed control results in higher robustness and improved transient response, the original dynamics of the system remain unaffected.
  • In this project, a hybrid continuous and critical conduction mode (HyCCM) modulation technique was developed which minimizes power loss attributed to buck-based electronic capacitor (EC), over a wide power range. While operating the silicon-carbide (SiC) MOSFETs-based ECs, the developed HyCCM technique dynamically operates in soft-switched CRM and hard-switching CCM within a one-double-line frequency cycle, based on the DC load current. As a result, power loss attributed to EC is minimized over a wide power range, making it suitable for high-power applications.

    Multi-functional Integrated PMSM based On-board Charger

  • A higher gravimetric and volumetric power density in the on-board charger was attained by employing an integrating set of components for charging the HV battery, LV battery, and traction purposes. A permanent magnet synchronous motor (PMSM)- based on-board integrated electric vehicle (OBIEV) charger with AC winding currents, has issues of instability, torque production, increased current ripple, and EMI due to varying winding inductance.
  • In this project, an integrated on-board charger is presented that maintains input power quality and synchronously performs active power decoupling with same components reutilized for charging LV battery. In order to limit the increase of winding current ripple, grid current total-harmonic distortion, and EMI, the inductance variation behaviour is studied. To mitigate these adverse effects, a variable switching frequency pulse-width modulation (PWM)-based modulation strategy is developed. Moreover, an adaptive PR controller for each motor winding current control is implemented for zero torque production and system stability in charging mode. This control/ modulation approach allows for the stable operation of the integrated on-board charger during the charging process. Circuit verification was done using 1kW IGBT based hardware setup.

    Current/ Voltage Senor Reduction in various Electronic Capacitors

  • Development a 1kW IGBT based experimental setup to validate sensorless operation of buck based active power decoupling converter using fixed frequency based modulated-model predictive control (MMPC). The MMPC algorithm is introduced for APD circuit which aims to improve its performance under non-ideal grid conditions. In MMPC algorithm, a voltage vector is formulated to track the reference ripple power. Moreover, a decoupling-voltage sensorless operation is achieved by MMPC algorithm by reconstructing the dynamic model of the APD circuit based on Euler’s approximation.
  • To achieve improved performance and current-sensorless control, this work presented an adaptive non-linear current observer (ANCO) based control for series-stacked buffer. Without using any differential functions, ANCO based control technique for SSB control is also able to provide disturbance rejection caused by parameter mismatch. Moreover, due ANCO’s noise filtering capability, reliable performance of SSB is facilitated.

    Comparsion of Different Modulation Strategies for 3-Phase VSI

    In this work, various modulation techniques of a three-phase voltage source converter were compared, analyzed and examined for their performance in generation for a sinusoidal output. Modulation techniques include Sine-PWM, Space-vector PWM, Delta-Sigma, Model Predictive Control and Modulated Model Predictive Control. MATLAB/Simulink and Hardware implementation of different modulation techniques was verified on 1kW IGBT based 3-Phase VSI using D-Space(RTI 1104).
