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 Variable Switch Mode Power Supply (SMPS)

So far in this website we have studied LM317 based linear power supply circuits, here we will learn how an LM317 can be executed as a variable switch mode power or SMPS with zero loss. LM317 as Linear Regulator We all know that an LM317 IC is internally designed to work as a linear voltage … Read moreLM317 Variable Switch Mode Power Supply (SMPS)

0-60V LM317HV Variable Power Supply Circuit

The high voltage LM317HV series of ICs will allow to go beyond the traditional voltage limits of an LM317 IC and enable controlling supplies that may be as high as 60V. 0-60V Regulation with a Single IC LM317 Therefore now you can build a universal 0-60V regulated power supply circuit loaded with all the essential … Read more0-60V LM317HV Variable Power Supply 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. The idea was requested by Mr.Praveen. Technical Specifications My name is Pravin, I work in school as Physics … Read moreSimple RGB LED Color Mixer Circuit using LM317 IC
