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 […]

How to Generate Electricity from Shoe while Walking
In this post I have explained how to generate electricity from our shoe while walking. This electricity can be simultaneously used for charging a cellphone battery. In a few of my previous posts I have explained how simple machines can be efficiently used for extracting free electricity, you may learn more on this through the […]
Pure Sine Wave Inverter Circuit Using IC 4047
A very effective pure sine wave inverter circuit can be made using the IC 4047 and a couple IC 555 together with a few other passive components. I have explained the details below. Introduction In one of my previous posts I explained the main specifications and datasheet of the IC 4047 where I have explained […]
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 […]
Pseudo-sinusoidal IC 4047 Inverter Circuit
From a continuous source, battery, or vehicle alternator, it is possible to produce a 50 Hz voltage/pseudo-sinusoidal waveform, using this simple IC 4047 inverter circuit. The design is capable of operating many low-power devices that require a voltage of 220 V AC, typically supplied by the AC mains grid distribution network. The power of this […]
