This is a simple 230 V LED Driver circuit which is accomplished using a capacitor based power supply. This is a low cost and efficient circuit and can be used at homes. Here we design a simple circuit ...

This is the circuit diagram of bipolar LED Driver using microcontroller. Here we use an LED which has a forward voltage drop of 2.2V and hence can be biased using a 5V supply. This Bipolar LED Driver ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

SOME MULTI-STRING LED MODULES come with a common-anode configuration. The commonanode connection reduces the number of wires between the LED module and its driver from 2N to N+1, where N is the number ...

In this paper, the driver circuits are proposed for Light Emitting-Diode (LED) lamps with a dimming feature. The two different drivers used are flyback converter and forward converter in series with ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...
