Jun 3, 2022 Hi, I'm searching for an example circuit to be run on LTSpice with a SMPS together with a common mode choke. The idea is to run a transient simulation in order to see the effect of this latest component on output voltage (noise reduction). Do you have anything to … From bing.com
SOLVED - SMPS - UC3842 ULVO ISSUE - ALL ABOUT CIRCUITS
Sep 26, 2024 Background I'm repairing a monitor with a SMPS utilizing a UC3842 IC. I've tested the monitor in my shop and worked fine. When I get to the customer's site, it wouldn't startup. The difference is the input AC (My shop = 120 to 130 VAC. He's shop is 118VAC). At his site, I … From bing.com
I WANT TO TURN A BOOST SMPS INTO THE SIMPLEST AUDIO POWER AMPLIFIER.
Nov 8, 2024 I'm trying to turn a Boost into a Flyback and then into an audio amplifier. Basically I wanted a simple SMPS modulated with an audio signal. I know, you will say that the class D amplifier is also an SMPS, but the class D amplifier needs at least 2 power transistors + a large... From bing.com
DESIGNING FLYBACK TRANSFORMER FOR SMPS | ALL ABOUT CIRCUITS
Mar 31, 2025 hello, I was trying to build SMPS using switching ic's UC3845 or HVLED007 but ending with less current delivery or poor power factor might be due to improper flyback transformer design. the thing is i don't have the bobbin , core datasheet were i can get all the specs currently i have...

REPAIRING SWITCHED MODE POWER SUPPLIES (SMPS) - ALL ABOUT …
Nov 1, 2007 Very often when I attempt to repair electronic devices, either mine or from friends, I find out the problem is with the power supply which these days is most often a Switched Mode Power Supply (SMPS). Most of them are flyback, regulated, SMPS (but not all!). In this post I will be discussing... From bing.com

PROVIDING THE EARTH GROUND TO THE DC OUTPUT OF SMPS
Jul 2, 2024 Prior to making a solid connection between the SMPS negative output terminal and "actual earth ground." I suggest measuring the voltage between those two points. From bing.com
Dec 17, 2024 I made a simple smps with uc3845. The output of the ic is connected to IRF840 and a EE30_15_7 ferrite transformer wound by me. The osc section seems to be working. Vcc supplied is 16.5 v Pin 1 connected to opto coupler pin 2 to GND Pin 3 to the 0.47ohm resister connected between Mosfet... From bing.com
