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 […]

3 Best Transformerless Inverter Circuits
As the name suggests, an inverter circuit that converts a DC input into AC without depending on an inductor or a transformer is called a transformerless inverter. Since an inductor based transformer is not employed, the input DC is normally equal to the peak value of the AC generated at the output of the inverter. […]
Inverter Voltage Drop Issue – How to Solve
Whenever PWM is employed in an inverter for enabling a sine wave output, inverter voltage drop becomes a major issue, especially if the parameters are not calculated correctly. In this website you might have come across many sine wave and pure sine wave inverter concepts using PWM feeds or SPWM integrations. Although the concept works […]
Arduino Pure Sine Wave Inverter Circuit with Full Program Code
This article explains a simple pure sine wave inverter circuit using Arduino, which could be upgraded to achieve any desired power output as per the user’s preference. Circuit Operation In the last article I have explained how to generate sine wave pulse width modulation or SPWM though Arduino, we are going to use the same […]
SG3525 Full Bridge Inverter Circuit
In this post we try to investigate how to design a SG3525 full bridge inverter circuit by applying an external bootstrap circuit in the design. The idea was requested by Mr. Mr. Abdul, and many other avid readers of this website. Why Full-Bridge Inverter Circuit is not Easy Whenever we think of a full bridge […]
