Abstract
Existing EV chargers use a strong non - linear diode bridge rectifier to deliver Direct Current voltage at the DC-DC converter's input, which degrades input AC current power factor. Due to these issues, typical battery chargers must eliminate the input bridge to improve power factor. This research paper main aim to improve the front end power factor by using bridge less landsman converter. It is combination of PFC converter and isolated fly back converter to operate between constant current and constant voltage modes. The modified PFC should achieve the constant DC-link voltage and improve the power factor up to unity. It also provide the improve in power quality, low device stress, low input and output ripples, and low input current harmonics when compared with bridge converter.
