    My 1.5KW PFC test @ 100VAC input

    Here is my test video of 1.5KW PFC with 100VAC input. The mains was setup down from 240VAC using a transformer to get 100VAC and then fed to PFC input, rest is you can see the performance in video, the resistive heater is 94ohms, output DC is 374VDC stable. The test was done for duration of 1hr...

    The non isolated offline buck converter

    For SMPS and PFC frontend we often need 12-24VDC supply which comes from AUX supply sometimes a small transformer or another flyback regulator which adds to cost and size. I just made a BUCK converter which is non-isolated, means direct referenced to mains rectified DC. It will provide the 24V...

    DO's and Dont's for making a good PFC.

    Making my contribution in good manner, since my friend complains me that i don't contribute much, so here it is. To make a reliable PFC. 1. You need a good inductor which should not saturate at the worst possible RMS INDUCTOR current. In other words, the required inductance at that current...
