While experimenting with a 300V DC to 220V AC inverter circuit, I noticed a strange overunity phenomenon which appeared to be like the generation of free energy from the inverter transformer. Recently while experimenting with a high voltage converter circuit, I was quite astonished to see a strange overunity kind of occurrence wherein the inverter […]

SG3525 Inverter Circuits with Low Battery Cut-off and Overvoltage Regulation
In this post I have explained a 3 powerful yet simple 12V inverter circuits using a single IC SG 3525. The first circuit is equipped with a low battery detection and cut off feature, and an automatic output voltage regulation feature. You may also want to read how to design a sine wave inverter from […]
IC IR2111 H-Bridge Inverter Circuit with Shut Down
This circuit is basically a H bridge inverter where two IC IR2111 are working for driving four MOSFETs that are connected in H bridge way. We also see that there is a overload and over current shut down using BC547 small transistors. So what happens is that we can run a load with AC waveform […]
