Converter for Induction Heating Nuts on the Basis of a Series-Parallel Resonant Network

The induction heating system converter based on series-parallel resonant circuit was considered. The necessary conditions to reduce the resonant circuit input current relative to the inductor current were determined as well as implementation of the inductive-capacitive converter properties. The basic design ratios to align the inductor parameters relative to the frequency converter were obtained. Experimental verification of the results was carried out.
