double sided inverter

[abhichaotic]

hi,
i have developed a normal dsp inverter in my lab which convert 110dc to 230v ac . now i want that when ac is present it will charge my batteries. i dont want to to use additional igbt's . currently the igbt which i'm using is k75t60. plz suggest me any schematic or idea to control the switching of igbt for converting ac to dc

Are you converting AC to DC or DC to AC?

currently mine inverter is converting dc to ac, i want that it also converts ac from mains to dc

You can use a transformer and a diode bridge, are you familiar with that method?

i want to make a controlled converter using igbt not the you r talking about. i just want to know the pattern of switching of these igbt's
