SWITCH MODE POWER SUPPLY

[jitendragorashia]

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.

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...
