IGBT based Three Channel Interleaved PFC Boost Converter for Inverter Front-End Application

In the proposed paper three stages interleaved boost PFC converter at 60kHz of switching frequency and 3.3kW of power rate with IGBT switches and fast silicon diode is described. The controlled rectifier front-end converter energies a general purpose IGBT single module inverter system used for induction or IPM motor drives. The PFC control circuit applied allows a flexible solution. The interleaved boost PFC stages number can be chosen depending on the output current request. In the paper a comparison of the dynamic performances and converter efficiency will be carried out at different active stages solutions. Furthermore, IGBT constraints for an optimized design of PFC converter are focused.
