Simple LED Forward Voltage Drop Tester Circuit

Last Updated on August 10, 2026 by Swagatam Leave a Comment

amber LED testing

Semiconductor LEDs (Light Emitting Diodes) produce light when current flows through them. In comparison to conventional lighting sources, LEDs offer a number of benefits, including high energy efficiency, extended longevity, and low thermal output. The forward voltage drop of an LED is one of the important factors that affects how well leds performs. We will […]

Difference Between Forward Converter and Flyback Converter

Last Updated on June 23, 2026 by Swagatam Leave a Comment

We know SMPS can be made in different ways, but two common ones are flyback converter and forward converter, which may look same at first. But inside working is not same at all, so this part matters before you design transformer or power stage. Audio/Video Representation Flyback Converter We see a flyback converter works in […]
