{782} 12 Volt SMPS Have Only 3 Volt Output, Low Output

12 Volt SMPS Power Supply Have Only 3 Volt Output. in this video number {782} i demonstrated and explained how to repair TL494 / KA7500 based half bridge 12 volt 20 ampere smps rafeed model RF-0076, it was providing low output voltage than the rated 12 volt, and there was no control by voltage adjustment potentiometer. i found the pwm controller ic tl494, it was damaged. i replaced the smps controller ic with new one and the power supply started functioning normally

Fundamentals of Power Electronics – Switched Inductor Operation

Introduction to switched mode power supplies and how the inductor can operate in the power supply. The voltage over the inductor is generally switched between two different voltages and it can generally operate in continuous conduction mode (CCM) boundary (or critical) conduction mode (BCM) and discontinuous conduction mode.
