PROJECT DESCRIPTION

The project is designed for battery charging control using thyristor triggering control system. AC power is applied to the bridge rectifier comprising diodes and a TRIAC getting desired control from the microcontroller.

The project uses zero crossing point of the waveform, which is developed by comparator whose output is then fed to the microcontroller. The microcontroller provides required delayed triggering control to the 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 is used in our project in place of the battery. The output DC voltage is measured using a multimeter.

This project uses a microcontroller from the 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 load bridge rectifier for achieving higher voltage control for charging a number of batteries in series.

Q & A
Q:  Which microcontroller is used in this project?
A:  The microcontroller used in this project is a 40 pin IC from 8051 family.
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 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 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.
