Induction heating is a non contact method of heating a conductive body by utilizing a strong magnetic field supply frequency 50Hz or 60Hz. Induction heaters incorporate a coil directly fed from the electric supply typically for lower power industrial application where lower surface temperatures are required. The aerospace power frequency for specialized induction heaters operated 400 Hz. Induction heating was used in industrial and household applications from early 19 th centuary. It has the advantage that energy efficiency is above 85%. The normal heating can only transfer 74% of its energy. Proper bearing installation is essential to the long life of rotating machines by induction heaters have historically been the best method for ensuring bearing installations. The energy efficiency is reduced with the number of stages of conversion. The reduction of conversion stages and also the increment of the energy efficiency of the system are required. The main drawback related to power factor correction convertors is the increment of electromagnetic interference. The high frequency noise must be filtered out in order to ensure compliance with EMI European standards. This project deals with the normal rectifier replaced by bridgeless boost rectifier. The capacitor bank provides the smoothening of output voltage. Series and parallel capacitors at the load side provide the reduction of harmonics and also the power factor correction. Thus there can be the high frequency parallel resonance bridgeless boost rectifier with induction heating applications.
