Open Source 6KW PFC Charger

Here is a 6KW Power Factor Corrected Charger I designed for charging electric vehicles. Charger is designed to be powered from 84 to 264VAC Single phase power. Charger then boosts and power factor corrects the incoming power to 400VDC and stores it in a 150uF film cap. Output of the charger is a High-Side buck converter based on a 400A 600V IGBT
