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. Audio/Video Representation Why Full-Bridge Inverter Circuit is not Easy Whenever we think of a […]

Understanding SG3525 IC Pinouts
In this article I have explained the pinout functions of the IC SG3525 which is a regulating pulse width modulator IC. So I have explained in details: Main Technical Features The main features of the IC SG3525 may be understood with the following points: Pinout Diagram of the IC SG3525 PinOut Description A practical implementation […]
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.

Simple SG3525 Sine Wave Inverter Circuit Explained
In this post we will discuss two methods of designing pure sine wave inverter circuits using 555 IC based SPWM processing. In the first concept we connect the 555 processors directly with the SG3525 outputs and do the sine wave conversion directly at the MOSFET gates. In the second concept we do it externally and […]
