Abstract
Dry-type transformers have been successfully used for more than 30 years in power electronics ac and dc drives and they operate correctly. Oil-filled transformers with paper insulation are also used in power electronics circuits, for instance in small power plants, in electric heating (for furnace supply). The paper insulation in these transformers degrades quickly. This is due to commutation of power electronics elements, which is accompanied by overvoltages between transformer winding and tank, with voltage change rate greater than 100V/μs.
