Abstract: In the modern era, the electronic equipments are widely used and it is required to maintain the supply current harmonics within the standards specified by IEC. Efforts are taken to get better power factor of these supplies using Bridgeless Interleaved Boost Converter (IBC) topology. The efficiency and the power factor of the bridgeless converter is improved in contrast to the conventional PFC as the bridged structure is eliminated. Main objective of the paper is to propose a novel Zero Voltage Switched Bridgeless IBC. This bridgeless configuration is investigated by analyzing the attributes such as output power, mark-space ratio, source voltage, input current with each other. With zero-voltage switching, the voltage regulator can engage in soft switching, which helps to minimize switching losses and electromagnetic interference. This paper also compares performance parameters such as power factor, efficiency, THD and ripple with and without ZVS in a bridgeless IBC circuit. The results show that there is a considerable ripple reduction and power factor improvement with increase in efficiency on incorporating soft switching. Replication of the projected circuit is executed in simulation and the outputs are verified using hardware implementation.
