I have attached the two topologies of rectifier. One works well for lower input amplitudes and the other for higher input amplitudes.
In order to achieve max efficiency for low as well as higher input amplitudes, I need some adaptive control mechanism which can select rectifier topology based on input voltage.
So, How can I select and design a control circuit which can select either of the topology based on the input voltage?
