Single LM317 based MPPT Simulator Circuit

To make this simple MPPT circuit we first modify a standard LM317 power supply circuit into a buck converter then configure it with a solar panel for implementing an MPPT function. Modifying a LM317 Power Supply into an MPPT Solar Optimizer In our previous article we learned how a standard LM317 power supply could be … Read moreSingle LM317 based MPPT Simulator Circuit

LM317 with Outboard Current Boost Circuit

The popular LM317 voltage regulator IC is designed to deliver not more than 1.5 amps, however by adding an outboard current boost transistor to the circuit it becomes possible to upgrade the regulator circuit to handle much higher currents, and upto any desired levels. You might have already come across the 78XX fixed voltage regulator … Read moreLM317 with Outboard Current Boost Circuit

Simple RGB LED Color Mixer Circuit using LM317 IC

The post explains a simple LM317 IC based RGB 3 watt LED color mixer circuit, which can be used for demonstrating the color mixing effects of red, blue, green colors as specified in the standard color charts.
