- SMPS with UC3845 - All About Circuits
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
- I want to turn a Boost SMPS into the simplest audio power amplifier.
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
- Providing the earth ground to the DC output of SMPS
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
- USB and SMPS Leakage Current - All About Circuits
USB Charger (and SMPS) AC Leakage Experiment To confirm my beliefs and to correct some erroneous information presented in this post My Mobile Charger Shocked Me While Charging, and other posts in this forum, I conducted an experiment Call it put up or shut up Belief #1 USB chargers and by
- How to modify a switch mode power supply. | All About Circuits
This thread is a carry-over from one that i started earlier on a SMPS that wasn't working The problem with that supply has been solved and is now working fine My next project is to build a battery charger using that supply, only problem is the output is +31 5 volts DC which is far too high for
- SMPS set to output 12. 81V (it is laptop 20V power supply), but it . . .
I have an SMPS set to output 12 81V (it is laptop 20V power supply), but it fluctuates between 12 2V and 12 8V at idle, which is around 6% It stabilizes at 12 81V under a load, I tested it on 1 5A Is this kind of fluctuation acceptable for an SMPS on idle, and could it potentially damage the
- about Power Factor Correction - All About Circuits
PFC is a circuit which corrects the current and voltage phase shifts to increase efficiency and it provides 360v or 400v at its output which eliminates the line regulation for the SMPS circuit and also some PFC cancels out input harmonics noise to improve power factor We took television power
- **The Official Guide to Special Masters Programs**
SMPs are generally programs designed for several different populations of students 1) Those who completed their science requirements in college and need to improve their academic standings (mostly low GPA issues)
