The project is designed for charging batteries by DC from AC power supply. DC power for a battery charger is derived from a thyristor controlled rectifier system. AC power is applied to a bridge rectifier comprising of diodes and a triac getting desired control from microcontroller.

The project uses zero crossing point of the waveform which is detected by a comparator whose output is then fed to the microcontroller. The microcontroller provides required delayed triggering control to a triac through opto isolator interface.

Finally the power is applied to the load through the triac in series with the bridge rectifier. The rectified and controlled DC output is given to the load i.e., a resistor used in our project in place of a battery. The output DC voltage is measured using a multimeter.

This project uses a microcontroller from 8051 family which is interfaced through push button switches used for increasing or decreasing the DC voltage for proper charging purposes.

The project can be further enhanced by using direct 230 volt supply instead of 12 volt AC to the bridge rectifier for achieving higher voltage control for charging number of batteries in series.

Q & A
Q:  Which microcontroller is used in this project?
A:  A 40 pin microcontroller from 8051 family is used in this project.
Q:  What is DC power control?
A:  DC power control is controlling the DC power applied to the load using a thyristor controlled bridge rectifier.
Q:  What is ZVS?
A:  ZVS is zero voltage sensing, used to detect the point on the time/frequency axis, when the AC voltage is zero. In other words, it generates a pulse for every zero crossing of the AC signal waveform.
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 was searching for the projects in google then my friend has informed me about edgefx and gave me the edgefx details. So, i have directly visited the edgefx website.
I have decided to buy project from edgefx because the visuals i saw in the website it was properly assembled. I like complete kit of the edgefx especially the presentation of the kit.
the kit was delivered in time with right components.
the support team has helped me purchasing the project.
as my friend gave reference to me. And, i want to give reference to other friends and juniors..

While I was searching for the projects, My friend informed me about the URL i.e., www.edgefxkits.com. I decided to buy a kit from Edgefx because the Hardware is assembled properly. I like the complete DIY kit.Yes the kit is on time.No I directly purchased through online.Improvement should be in Technical Aspects.
