Abstract:-This paper presents new buck type power factor corrector rectifiers that operates in
continuous-conduction mode (CCM) and generates a multilevel voltage waveform at the input.
The proposed transformer less, reduced filter, and multilevel rectifier topology has been
investigated experimentally to validate the good dynamic performance in generating and
regulating dual 125-V dc outputs terminals as telecommunication board’s feeders or industrial
battery chargers under various situation including change in the loads and change in the main
grid voltage amplitude. Due to CCM operation, commonly used ac-side capacitive filter and dc- side inductive filter are removed from the proposed modified packed U-cell rectifier structure.
High power factor or PFC boost converter is used in model which operates in boost mode. IGBT
is used for switching operation and Model works on 50 Hz frequency it uses Less no. of system
switches which reduces the system stress and Less number of switches reduces loss in power and
also makes circuit simple and cheaper.
