Here you have an example of 220ac/12Vdc smps: However, if you don't feel confident about HV ferrite transformers then you should consider a step-down transformer 220/24Vac + bridge + smoothing cap, and a switchmode dc/dc converter build around sme 5A IC, such as for example LM2768: www.national
The easiest way is to use a small transformer and step down voltages from 220/110 to 5Vac, then rectify this and measure it on a 0-5Vdc ADC.. Good luck.. IanP
Electronic transformers 200 W shematics (220/12 V) Feron transf. needed. Can anybody upload it?
You can try this method: connect a small 220/12 (or less) transformer between each phase and Neutral (I asume you have access to N or E, in isolated circuits the primary should be rated for 400V and connected betwee phases). If you want to monitor each phase separately you will need 3 circuits with OR function at the final stage. Rectify the volt
I don't understand if you want put it inside the screwdriver... however you can use a simple transformer of about 40VA 220/12Vac ,a C filter and a zener/bjt voltage stabilizer made by a TIP 41, 2n3055 or other. Lollo
I have a VHF radio and I want to make a power supply for it, I have a nonlinear switching regulator from TI , Thanks TI :), having a rating of Vin 18-36V, Vo 6.5 - 17.5 V, 8.5A, 100W. My questions are the following: 1.) Can I use a low current transformer at the input say 110 - 220 Primary and 20V Secondary having only a 0.5 A current and wit
For low power (< 50W) you can use sinwave generator (eg. ICL8038) and just amplify this signal using linear amplifier and 12/220 transformer connected opposite way around. Tha output will be nice sinewave but unregulated ie. depending on load the voltage may drop 5%...15%.... If your power requirements are higher I would't bother. There is no si
Who can to help me with a schematics for power inverter 12 v DC to 220 AC which provide 3500 Watt to outpout. I want to use this inverter to supply my house (tv, mixer ,computer etc)
I looking for power supply circuit that input 110to220V AC output 12V DC 1A but don't use transformer like mobile wall charge, notebook.. etc. a tiny circuit is very good. How you call this circuit ? I don't know keyword to search. Because I am Thai. Have a good day.
