Boost Power Factor Correction Converter fed Domestic Induction Heating System

Unique advantages of induction heating (IH) technology in terms of efficiency and performance has increased its endorsement in industrial along with domestic applications. Owing to this, the usage of IH technology for domestic cooking is being increased and the increasing application of this technology is leading to power quality issue in terms of THD, low power factor problem and electromagnetic interference (EMI) effect. In order to mitigate these issues, in this paper a domestic IH system has been designed using boost power factor correction (BPFC) converter which acts as a front end converter. The BPFC converter corrects the input power factor (PF) as well as regulates the DC link voltage. This DC link voltage is fed to the full bridge series resonant inverter (FB-SRI) which generates high frequency AC which is the need of domestic IH system. A 2.2 kW domestic IH system has been designed and validated through the Power simulation (PSIM) software.
