Power Electronics

The power electronics group at the IES has gained experience in power electronics design of various topologies and applications in the recent past. We specialize in the lower power range of a few watts to a few kilo-watts where switched mode converters are employed. Our expertise includes PWM converters of many topologies and power classes, soft switching concepts and innovative resonant topologies. Our team includes magnetics specialists who design optimized complex magnetic structures such as integrated magnetics.

We analyze, evaluate and design power converter stages for applications like wall adapters, grid and drive inverters, high voltage supplies, wireless power transfer and more. They are employed in industrial and consumer electronics, power distribution, battery chargers, IT appliances, and electric and hybrid-electric vehicles.

The project scope can comprise feasibility- and variant studies, analysis and simulation, design and development op prototypes up to production level.
