This is a dangerous project. It generates high voltage and high current. It is not for newbies.
Today I will build a 500W electric fishing. Use 12V battery. It has 10 mosfet IRF3205. Very strong and cool. The controller board uses KA3525 with totem pole driver. EI40 pulse transformer.

All my projects are free, I design them on EAGLE 6.0. I uploaded it to Google drive. You need to use a web browser to download the file and open the file with winrar software (extract) on the PC. Open schematic file (.SCH) and PCB file (.BRD) with EAGLE software. Hope you enjoy my videos and projects.
