Want to make modification on my (kuteng) KT 12 MOSFET sine wave controller. My idea is to cut bottom part of controller (red lines on picture) and solder to the same pins of existing mosfet. In result from 12 mosfet will become 24 mosfet controller. New fets will be installed upside down and bend 90 degree. They will be attached to new aluminum sheet which will perform as heat sink. Thermal paste between aluminum plate and controller case. Of course i am going to add some extra capacitors. What do you people think about this idea? Let me know in comments.
