Full wave rectifier with a high DC offset voltage?
No, you can't do that. If you have 5V peak-to-peak riding on top of 100V dc then two of the rectifier diodes will always be forward biased. The other two diodes will see a combined reverse voltage that varies from 95V to 105V. On the other hand, it really doesn't make sense to use a rectifier when the input voltage is always positive.
