| How to make Power supply without Transformer? |
A 230V LED Driver circuit without using a transformer, the count it can be increased at your convineance. Due to the absence of Transformers we can reduce the cost and size of the circuit considerably. LED's are Cheap, efficient and cool device with low power consumption, so our electricity bills will be reduced to a great extent.
LED's commonly works only in DC, so we have to convert the alternating current to direct current and step down to a safe value before applying to the led sequence
Circuit Diagram:
Components Required:
- 5 LED Bulbs
- Rectifying Diodes (4 × 1N4007)
- Electrolyte Capacitor (47uF)
- Zener Diode (12v 1W)
- Polyester Capacitor (0.47uF 400V)
- Resistance(2 × 120 ohm 1/2W ) and (470k ohm 1/4W)
Note: The circuit is powered by 230V 50Hz ac
supply, so be careful while troubleshooting this circuit.
Hey, here I am found a video of How to make Power supply without Transformer?
IF you face any problem related to this project comment in the comment box our team tries to resolve it. :)
Power supply
Power supply is the device which is give smooth DC by rectifying the AC signal. In which haved protection devices like NTC and PTC etc, Which is protect the device.
Transformer
It works on the principle of mutual induction. Since the induction is the property of a.c. circuit only, therefore a transformer can work on a.c. only and not on d.c.
Note: An auto transformer works on the principle of self induction.
Note: An auto transformer consists of one winding only
which is divided into two sections named as primary
and secondary.
Note
Make it on your own risk, it's extremely dangerous to work with AC mains without proper experience and precaution. Do take extreme caution while building this circuit.
