DIY kit comes with an Assembled and Tested PCB ensuring 100% output guarantee. Includes hardware for assembling project from scratch. Fully supported by elaborate documentation, audio visuals and tools to independently carry out the project work.


Dual converter is a power electronics control system to get either polarity DC from AC rectification by forward converter and reverse converter . It can run a DC motors in either direction with speed control too .

This single phase converter is achieved by using a pair of thyristor controlled bridge (4 SCRs X 2 ) that enables the DC motor to get reversed polarity for either direction rotation and speed control also lowered in steps by Microcontroller triggering each bridge SCR bank of duly interfaced through opto-isolators.

A pair of switches is used to input logical signal for the desired output. If input of 230 volt ac is given to the dual SCR bridge we can have a 100 watt lamp load and the DC polarity across the lamp is checked. Alternatively we can use 12 volt ac at the input and a 12 volt DC motor to verify either direction rotation as the polarity gets reversed.

The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.

Q & A
Q:  What is dual converter?
A:  Dual converter is a power electronics control system to get either polarity DC from AC rectification by forward converter and reverse converter using 2 full bridge SCR's.
Q:  Which microcontroller is used in this project?
A:  A 40 pin microcontroller from 8051 family is used in this project.
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.

I came to know about Edgefx through one of my senior.
I decided to buy a kit from Edgefx by the words of my senior
Purchased directly through online.

I came to know about Edgefx while I was searching for my Academic project in Google along with my friends.
Since Edgefx is providing project kit also so decided to buy my project from Edgefx. I liked the circuit diagrams and explanation of video.
I placed an order through online.
