  High Voltage, High Repetition Rate Pulse Generation Semiconductor Devices


   School of Physics

   Monday, March 31, 2025  Funded PhD Project (UK Students Only)

About the Project

High Voltage, High Repetition Rate Pulse Generation 

About the PhD Project

Are you passionate about developing novel research and keen to shape the future of energy transfer technologies in areas such as RF technologies, pulsed power, semiconductor physics, materials science and engineering, and next generation power electronics? 

We are recruiting a motivated PhD candidate to undertake an exciting project with funding provided by the EPSRC Energy Transfer Technologies Doctoral Training Hub. As a student of the Hub, you will receive an enhanced stipend of £23,237 per year, plus additional funds of £7,000 a year for travel, conferences and research equipment.

This project is co-funded by MBDA UK Limited and hosted at the University of Bristol. The successful candidate will be based in the Centre for Device Thermography and Reliability (CDTR) and aligned with the REWIRE Innovation and Knowledge Centre. 

The studentship will focus on the generation of short, fast rise-time, high-voltage electrical pulses using entirely solid-state means. The aim of the project is to research and develop methods and technology that advance the current state of the art, working towards solutions that can provide suitable output waveform characteristics at a very high repetition rate with low jitter, high efficiency and high reliability. 

High performance solid-state pulse generators are creating significant international interest, but few groups have come close to achieving the performance required for the most demanding applications. It is hoped that the progress achieved during the course of this work will support the UK in realising a world-class capability in this technology by developing novel solid-state pulse generation devices using wide and ultra-wide band gap semiconductor materials.

The main objectives of this project are:

·        Investigation of existing and novel methods of solid-state pulse generation

·        Research into novel semiconductor devices suited to high-voltage pulse generation

·        Development of power conversion circuits optimised to drive existing and novel semiconductor devices, to generate appropriate pulses with high efficiency

·        Measurement of semiconductor device characteristics and performance of prototype pulse generator circuits

The skills acquired during the studentship will be widely applicable across industrial, medical and defence sectors.

The Hub

The Doctoral Hub specialises in developing research and training the next generation of leaders in energy transfer technologies for defence and related sectors.

The successful candidate will be based in the Centre for Device Thermography and Reliability (CDTR) at the University of Bristol. The CDTR is a world-leading research centre focusing on developing next generation semiconductor electronic devices for net zero, communications and radar technology by improving device thermal management, electrical performance and reliability, using wide and ultra-wide bandgap semiconductors. The PhD is closely aligned with the REWIRE Innovation and Knowledge Centre and will provide the student additional access to the network.

Throughout their PhD will benefit from the support and expertise of our diverse academic community, a community of students working towards similar goals, as well as our specialist industrial network.

How to apply

You will need (1) a CV, (2) a Personal Statement, which is a one- to two-page document introducing yourself and outlining your motivation for PhD research, and (3) a transcript of any qualifying degrees (completed and/or underway). You do not need a research proposal, but are encouraged to specify a research theme or academic supervisor. Applicants will be assessed on merit, and interviews will be held for shortlisted applicants. You need to apply through the University of Bristol application system at http://www.bristol.ac.uk/study/postgraduate/apply/. Please choose “Physics PhD” as course, and mention “High Voltage, High Repetition Rate Pulse Generation” as the corresponding studentship advert and “Martin Kuball” as the contact person.

Please specify “Bristol Physics Research Scholarships” on the application form as your source of potential funding. Early application is encouraged. The closing date for applications is 31 March 2025.

Equality, diversity and inclusion

The Hub is committed to improving diversity within the sector and as such we aim to provide an inclusive environment in which all students can thrive. We particularly encourage applications from women, disabled and Black, Asian and Minority Ethnic candidates, and students from low-income/ non-typical backgrounds to apply. We can also consider part time PhD students.
