i am building a 2Kw battery charger for an EV conversion. stage one is pfc (Power Factor Correction). i had it working for a little while until it blew, had the wrong code on the controller, wasn't monitoring anything, i have no clue why it blew. plan to re code from the beginning.
i have tested a buck converter at 1kw, will be building a new one to add as stage two, rated for 2kw.
FPAB20BH60B - Ti - all in one power stage.
random discrete components.
atmega8 - avr - the controller
NGTG15N60S1EG - IGBT
KCF25A40F - High Power Diodes
ACS712 - Current sensor
