SWITCH MODE POWER SUPPLY

SWITCH MODE POWER SUPPLY

SWITCH MODE POWER SUPPLY

(OP)
I have heard a lot about electronic equipment operating under very wide voltage range e.g. 90 volts A.C 60 hertz to 270 VOLTS. When inquired I have been informed that it works by switched mode power supply unit. Can any body provide further informationon on switched mode supply.
  

RE: SWITCH MODE POWER SUPPLY

What kind of information you are inquiring? Do you need some books to read, if you do let me know and I will provide you with names.

I am a SMPS designer myself. Just let me know what are you looking for and I will provide

RE: SWITCH MODE POWER SUPPLY

in SPS, some ways can be used to make the full range input.
1. add a PFC stage before Dc-Dc stage.
2. add a auto_range circuit.
3. using Flyback topology.

Also, we have some advanced topology to make it. Like, single-stage isolated rectifier with power factor correction...
