个人简介
At Virginia Tech, he pursues technologies for integration and packaging of power passive and active components to realize building blocks for power electronic systems. The integration strategy pursued divides the power electronic converter into three building blocks: Active, Passive, and Filter Integrated Power Electronics Modules (AIPEM, PIPEM, and FIPEM). Electro-magneto-thermal structures have been synthesized for realization of the functionalities expected from the structures. Materials and processes have been identified to verify the operation of the integrated structures. The structures, components, and interfaces have been subjected to thermal or power cycling, shearing, profiling, and spectroscopy analyses to assess their reliability. The AIPEM structure (e.g., an "embedded-power" module) contains the semiconductor devices, the associated ancillary functions (e.g., gate drives, sensing, and protection), and thermal management elements (e.g., heat spreader, heat sink, and micro-channel coolers). Interacting with the AIPEM to shape the conversion gain is the PIPEM (e.g., an integrated inductor/capacitor/transformer network) containing passive components designed to propagate energy at the switching frequency. The FIPEM (e.g., an integrated lossy transmission line for EMI filtering), on the other hand, contains passive components designed to attenuate at the switching frequency, or the frequencies beyond the useful power bandwidth. These building blocks can be integrated, with intelligence, into the energy-delivery path, starting at the load end and expanding to the network and the source end, to realize versatile, cost-effective, reliable, and sustainable energy systems.
