Abstract: A laboratory implementation of a two-phase travelling wave induction
heating setup is described. The focus is the development of a versatile power
control system for multi-coil experiments and parameter studies. The drive
system features high temporal accuracy, full real-time controllability, and
integrated measurement technology, analyzed step wise. The performance was
tested using a full pitch travelling wave inductor based on litz wire with a
flux concentrator from a powder material. Thermographic images from the
experiments are presented and the results are compared with simulations. The
challenges related to multi-coil configurations are explained, many of which
are difficult to predict from simulations.
