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.

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...
