TL494 SMPS – switching mode power supply

this is a prototype I have built for research purpose. Recently I have learned how to use MOSFET technology. 1x VGA cooler is used together with IRF9540 p-channel MOSFET. 20V/100A welding transformer is used as voltage source! With no load, DC output is about 60V. 1x 12V 50W bulb for testing. Actually today I tried a second bulb in parallel … Continue reading
