Control of Next Generation Naval Wide-Bandgap Power-Electronics Systems using Predictive Switching Sequences and Switching Transitions
Abstract
In this 3-year ONR project, a radically-new multi-scale control for wide-bandgap powersemiconductor device (i.e., WBG-PSD) based co"nverter (or WBG-Converter) will be pursued andits efficacy validated in real-time operation. What is unique about this multi-scale" control is itsability to achieve performance optimality for the WBG-Converter at the device level; or, stated inother words, it a""chieves (power-electronic) systems control at the device level. The synthesis ofthe overall control mechanism, realized under large""-signal stability bound, is essentially threefold:i) control the time evolution of the switching states (i.e., switching sequence)" of the WBGConverter;ii) control the transitional switching dynamics of the WBG-PSD; and iii) co-synthesizethe switching-sequence-based control (SBC) and switching-transition control (STC) mechanismsunder one unified control framework to achieve multi-scale opt"imality for the WBG-Converterencompassing energy-conversion efficiency, ~~/~~ and ~~/~~ device stress, and electromagnetic""noise. Finally, each of the control formulation outlined in i) through iii) will be validated usingsimulation and scaled experiment"al validation using novel WBG-PSD device actuator that enablecontrol activation and power actuation for the WBG-Converter. The impa"ct of the radically-newmulti-scale systems-at-device-level control approach is profound and is expected to demonstratethat, unlike"" traditional control in power electronics, which are typically limited to state and/oroutput regulation and transient-performance m""anagement, SBC and STC yield unprecedentedcontrol that goes far beyond state-of-the art and has significant beneficial impact for N""avy. Suchapplications include but are not limited to pulsed-power systems, fault-isolation and protection,solid-state transformers"", propulsion motor drives, electric/hybrid-electric vehicles, renewable-/alternative-energy systems. ac/dc systems, and microgrid."" Further, by integrating WBG-PSD~shigh-voltage and high-frequency capabilities to the new device control capabilities, operation of"(compact) WBG-Converter at significantly higher voltages and higher currents (far beyond thecapabilities of conventional Si devices) can also be achieved using series/parallel/series-paralleloperation due to on-the-fly device-dynamics modulation. The PI plans to engage his existing andnew DOD industry (WBG-PSD and WBG-Converter) collaborators with the outcome of the newwork towards the eventual goal of Naval-application-specific utilization and productization if andas relevant during the course of this project. Final"ly, on the educational front, this ONR projectwill engage the services of a qualified PhD student whose current research focus is i""n closeharmony with the core focus of the proposed ONR project. In addition, some of the results of theproposed research are also" expected to be integrated into existing courses ECE 445 (Analysis andDesign of Power Electronic Circuits) and ECE 545 (Advanced Po"wer Electronics Design). Thesecourses are taught by the PI and are taken by several undergraduate and graduate students. The PI,wh""o has already guided over 33 undergraduate senior-design projects at UIC, also plans to provideopportunities for advanced research" for US undergraduate students at UIC to learn from theadvanced ONR project by working closely with the PI and his PhD student.
