PhD candidate for developing concepts for active/passive EMI/input filters and tools for filter design optimisation

Opportunity Overview

The Laboratory for High Power Electronic Systems (HPE) at the Department of Information Technology and Electrical Engineering of ETH Zurich is engaged in pioneering research on power electronic converter systems. These systems are essential for future energy distribution, particularly for integrating renewable energy sources and advancing traction applications in electric vehicles. Our research also encompasses solid-state pulse modulators that serve medical applications and high-energy physics at institutions like CERN.

Research Project

We are embarking on a new research initiative to enhance EMI/input filters for power electronic converters, and we are eager to engage highly motivated individuals with a remarkable academic background. This project focuses on the crucial and interdisciplinary area of EMI/input filters, particularly in three-phase rectifiers and converters used in electric vehicles. These filters are vital for minimizing noise emissions and harmonics, thereby ensuring compliance with relevant standards and grid codes. Yet, they also present challenges, such as increased size of converters and reduced system efficiency, which can further impact system stability.

The emergence of cutting-edge semiconductors, such as wide bandgap SiC MOSFETs and GaN HEMTs, has led to higher switching speeds that contribute to noise at elevated frequencies. As a result, the design of filters must navigate the delicate balance between achieving optimal performance and minimizing parasitic effects and layout constraints. The project aims to tackle these intricacies by exploring innovative concepts for both passive and active filters, while also optimizing filter design procedures that account for attenuation, high-frequency losses, temperature distribution, and controller stability.

Responsibilities

• Investigate and develop new concepts for active and passive EMI/input filters.
• Create novel filter design procedures that focus on minimizing volume and losses.
• Build prototype systems for validating new design methodologies and perform comprehensive measurements in the HPE laboratory.
