Contract: Full Time/Fixed Term for three (3) years.

Supervisor:

Dr Mohamed Lamine Faycal BELLAREDJ, Assistant Professor

Department of electrical engineering, Universite de Moncton (Moncton campus)

Email: []

Context & Motivation:

Because of their extreme computational needs where workloads demand rapid and significant shifts in power consumption, next-generation high-performance computing (HPC) platforms used in machine learning, big data and artificial intelligence (AI) based applications (CPUs, GPUs, AI accelerators etc.) require high power demands with optimized power distribution networks (PDNs) to improve power efficiency and preserve power integrity. Integrated voltage regulators (IVRs) with integrated passives can play a key role as a part of the PDN in enhancing power efficiency and performance in HPC systems. IVRs either in package or on-chip, provide voltage regulation closer to the load, enabling miniaturization and modularity while reducing resistive losses due to shorter PDN interconnects, and enabling faster power management loops with better power integrity and savings. By minimizing power loss and simplifying the circuits design, IVRs contribute to better thermal management and thus to a higher overall system efficiency.

This PhD research project targets the development of novel composite magnetic materials and package-embedded power magnetic core inductors based on these materials, which will be used to implement high frequency and high efficiency IVRs for HPC applications.

Objectives:

-Fabrication, characterization and modeling of the composite magnetic materials.

-Modeling, fabrication, characterization and of the embedded power magnetic core inductors.

-Implementation of an IVR module for HPC using the fabricated power magnetic core inductors and characterization.

Candidate Profile:

• MSc degree in electrical engineering, physics, materials science, or a closely related field.
• Background in composite materials, magnetic materials and devices, additive manufacturing and micro/nanofabrication, power electronics, electronic packaging and integration.
• Experience with numerical simulation and analytical computation tools: Ansys HFSS, Matlab etc.
