WP3: Holistic design of modern EMC-compliant power electronics devices with cooling aspects

Each of the PhD Candidates involved in this Work Package will adopt a holistic design approach exploiting the novel materials from WP1 and the computational multi-scale, multi-physical models from WP2. DC5, DC7 and DC8 will focus on specific design aspects with a circuit simulator (MATLAB/Simulink). DC5 will develop a new time-domain algorithm to size the inductors of filters accurately the core characteristics, i.e. saturation and losses. DC7 will optimise the converter design accounting for the disparate time constants of the coupled electromagnetic and thermal phenomena in a harmonic balance FE circuit simulator combining dedicated sinusoidal and PWM basis functions. DC8 will aim at optimised winding structures of for transformers in resonant converters in which the leakage inductance is accurately estimated. DC9 will replace linear state-space models in model predictive control algorithms to build up a novel nonlinear controller for grid-connected converters with LCL filters. DC10 will develop innovative integrated filter topologies and magnetic arrangements, enhancing the performance and commercial feasibility of filters in high-power, multi-megawatt electric systems. DC11 will develop high-power density inductive components through exploring and optimizing cutting-edge manufacturing methods, significantly contributing to the efficiency and integration of HF power converters.
