PMcC-10 Researcher Integrated Magnetics and Power Circuit Design
The trend toward miniaturisation and ever increasing functionality for portable electronic devices is creating new challenges in the fields of electronic engineering, materials science and process development. A key performance requirement for portable devices is battery life and this can be significantly extended by using a “granular” power supply approach that enables unused functions in the system on chip (SOC) to be switched off. However this requires many miniaturised efficient power converters. In order to limit the output current ripple, power converters require energy storage and usually magnetic devices such as inductors and transformers fulfil this requirement. Traditionally, these magnetic components tend to be very bulky but for switch mode power conversion the value of the inductance required is reduced by using a high switching frequency (20 – 200 MHz). This makes the footprint of integrated magnetic devices feasible but requires magnetic material and devices that can operate efficiently at high frequencies.
Tyndall National Institute at University College Cork, has over the last decade, been a recognized world leader in the area of integrated magnetic components for electronic applications. Prof. Ó Mathúna from Tyndall, is the founder of the International Workshop on Power Supply on Chip and a Fellow of the Institute of Electrical and Electronics Engineering (IEEE) in the field of power electronics with the citation “for leadership in the development of power supply using micromagnetics on silicon”. In 2015, the Magnetics on Silicon researchers were selected as the UCC Research Team of the Year. Tyndall Integrated Magnetics research has demonstrated:-
In addition to integrated magnetics on silicon, Tyndall’s Integrated Magnetics research has addressed PCB embedded magnetic devices. To the present, a magnetic core is provided for both types of integrated devices using electrodeposited magnetic material and windings are fabricated for; magnetics on silicon devices using electrodeposited copper and for pcb embedded magnetics using internal copper tracks.
Tyndall has recently obtained more than €3m funding from Science Foundation Ireland (SFI), EU Horizon 2020 and Enterprise Ireland for further world class pioneering research and commercialization of its Integrated Magnetics technology. The SFI Principal Investigator funding obtained by Prof. Ó Mathúna is one of 24 such awards in Ireland. As a result of this funding, Tyndall is planning a number of strategic hires to expand the existing team.
Reporting to the Senior Researcher in magnetics design the post-doctoral researcher in magnetics design, will play a leading role in the delivery of world-class outputs and the generation of economic impact from research excellence in integrated magnetics devices and associated circuits. This post-doctoral position will help advance the development of a new generation of integrated magnetic devices, with increased efficiency and miniaturisation. A major part of the research will focus on the development of validated numerical and analytical models for integrated magnetic devices. The models will be used in device optimisation and to determine the requirements, in terms of materials and processes for such magnetic components. A further key aspect of the research is the optimisation of the overall converter system. Analytical / compact models for the various components i.e. switches, inductors and capacitors will be combined to create a converter circuit model. This will be used to evaluate the impact of circuit topologies, number phases, frequency etc on the overall performance.
The post-doctoral researcher will participate in research collaborations with both academic and industrial partners and contribute to the sourcing of research funding from industry as well as Irish, European and international research agencies. They will also contribute to the continued development of a ‘high engagement/high performance working environment amongst all staff by promoting Tyndall’s key values of Leadership, Excellence, Teamwork, People, Entrepreneurship and Optimism.
