Research Highlights

GaN-based Active Rectifiers for More Electric Aircraft

IPEG research lab at UIC (former PEAS research lab at KSU) developed a high power density compact power converters for more electric aircraft assuring high resiliency, robustness and efficiency. During the designing procedure, the effect of parasitics on steady-state operation are taken into account. Innovative design techniques are introduced to mitigate the parasitic effects in the targeted high frequency for single-phase active rectifiers. Certain design conventions in PCB layouts can lead to the asymmetrical parasitic inductances between positive and negative half switching cycles, which may further result in the asymmetrical steady state operation, higher electrical stresses, and higher thermal stresses. All these challenges are addressed during the design procedure.

 

Hierarchical Model Predictive Control for Cascaded Multilevel Inverter

IPEG research lab at UIC (former PEAS research lab at KSU) developed a a hierarchical finite-set model predictive control scheme for grid-tied cascaded multilevel inverters with independent active and reactive power injection capabilities. The proposed controller has a hierarchical framework to eliminate the computationally burdensome cost function optimization and associated weight factors of the control objectives. The control formulation approach allows for multi-objective optimization with an error-tolerance framework. The control scheme achieves active and reactive power control with switching loss minimization while extracting power evenly from the independent voltage sources.

 

Smart Photovoltaic Inverter with Grid Fault-ride Through Capability

IPEG research lab at UIC (former PEAS research lab at KSU) developed a single stage smart photovoltaic inverter in collaboration with Texas A&M University at Qatar. An autonomous model predictive control scheme is proposed for a single stage quasi-Z-Source grid-connected photovoltaic inverter to facilitate switching between modes of operation: maximum power point tracking (MPPT) and low voltage ride through (LVRT). The proposed smart PV inverter can respond to rapidly changing PV ambient and grid conditions and appropriately alter the current injection. The proposed controller is complemented by an observer-based MPPT algorithm with an adaptive step-size to quickly pull the PV toward and away from the MPP as necessary. The performance of the controller is verified experimentally for several grid fault and reactive power injection scenarios. The ultimate goal of this research is to develop autonomous control schemes for 1 MW medium-voltage SiC based photovoltaic cascaded multilevel inverter; this project is funded by QNRF.
