11 Threads found on edaboard.com: Smps High Voltage Supply
A 20 kHz inverter can work with primary switching smps, but only if they have fast input rectifiers and no EMI filters effective in the 20 kHz range. Otherwise it can damage the connected device as mentioned by betwixt.
To avoid possible damage, it's safer to rectify the inverter output on board and supply high voltage (...)

how to get +5v and -5v dual power supply using single 24v and ground ( 24v smps)

Hi. "Power Loss = (15V-5V).1A = 10W" Is that a decimal point or a multiplication sign, please? Does your ADC circuit really need 1 amp, or does it need 100 milliamps? The 7805 type are fine at 1W.
You could use several linear regulators, but I think that is wasteful: 15V supply into a 12V regulator into a 9V regulator into the 5V regulat

A very common type of power supply is called a Switched Mode Power supply (smps). If you wanted a mains to 28V power supply from the 230V mains,the input circuit would rectify your incoming AC, this would give, 230 X 1.4 ~ 325V DC. A high frequency switching circuit would run of this voltage (...)

Most problems occur in the horizontal deflection and power supply sections. The smps provides sometimes a means for safety shutdown if the horizontal output stage produce excessive high voltage or draw too much current.
-bad electrolytic capacitor in the supply line to horizontal driver (...)

Please can i confirm that this is a viable method for TL431/opto smps regulation with output voltage of 36V......................................
(The TL431 is only good up to 36V)

Can a smps ferrite-core tranformer used in reverse? Eg. can a 230v/ 12v smps transformer used in reverse (assuming that the same switching frequency is used) to get 12v stepped up to 230v? as anyone try it out? Thanks.

The high wattage of the resistor you've mentioned is choosen because of two reasons:
- the surge current is much higher than normal current during stable work of power supply and the resistor must withstand that current for shor period of time (it's usually no more that 100 ms)
- the maximum voltage the resistor is (...)

I dont recommend you to design a high volatge circuit best on smps it can be dangerous work
Any how you can go and find a referance design for high voltage smps in ON- SEMI site
All the best

I want to design a smps with these specifications:
Input voltage: 3 phase 380V (Line to Line)
Output voltage: 10VDC to 100VDC
Output Current: 400A
Output Power: 40 kW (= 400A x 100V)
Efficiency: larger that 90% at Full Load (= 400A x 100V)
Any block diagram or idea?

The task is not as difficult as it seems. I have some experience with building flyback converters up to 150W so I would use flyback smps to power that LED matrix.
