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. The Circuit Concept In the previous post I explained the main specifications and datasheet of the IC 4047 where I have explained […]
New Circuit Projects
IC 4047 Datasheet, Pinouts, Application Notes
The IC 4047 is one of those devices which promises an unlimited range of circuit application solutions. The IC is so versatile that on many occasions it easily outsmarts it’s close rival, the IC 555, let’s study the datasheet and pinout details of this versatile chip. Main Datasheet and Specifications: In-built oscillator with variable frequency […]
Driving 3-Phase Motor on Single Phase Supply
Driving a three phase motor on a single phase supply directly through ordinary methods can be difficult and dangerous. It requires accurately designed circuits for implementing the operations. Here I have tried to present one such PWM controlled three phase motor driver circuit. I have explained more. The circuit can be understood with the following […]
Maintenance Tips for Lead Acid Battery
In this post I have explained some of the crucial parameters related to lead acid battery maintenance tips for ensuring longer life to the device. The questions were asked by Mr. Raja Gilse, answered by me. What is Full Charge Voltage of a 12V Battery Question: What is the full charge volt of the 12 […]
Electronic Load Controller (ELC) Circuit
In this post I have explained a simple electronic load controller or governor circuit which automatically regulates and controls the rotational speed of a hydro-electric generator system by adding or deducting an array of dummy loads. The procedure ensures a stabilized voltage and frequency output for the user. The idea was requested by Mr. Aponso […]
I/V Tracker Circuit for Solar MPPT Applications
Optimizing power by tracking is the key feature which makes solar MPPT concept so unique and efficient, where the complex and non-linear I/V curve of the solar panel is tracked and switched for creating maximum optimal conditions for the connected load. The Circuit Concept I have been trying hard to design something that would in […]
