The power electronics team at the IES has extensive know-how in circuit design for a wide range of applications.
Our focus is primarily on the lower to mid power range, where switched mode topologies are typically used. They include classic PWM converters with various characteristics and power classes, soft-switching and innovative resonance topologies. Likewise, analysis and design of complex magnetic structures is one of our competences. We devise, evaluate and develop power electronics applications, such as DC-DC converters, power adapters, power factor corrector frontends, inverters, drivetrains, high voltage sources, wireless power transfer systems and much more. Typical applications are found in industrial and consumer electronics, power engineering, drive systems and charging technologies, starting from IT devices to electric vehicles. Project scopes include feasibility studies, evaluation of variants, simulations and analyses, developments and realizations of prototypes up to the industrialization of complete designs.
