The bridge is connected as a voltage doubler. Two of the diodes in the bridge do nothing in this configuration.

I am curious about two things, at least. I understand the isolation transformer, but why step up or down?  Could it not just be a 120 to 120 VAC? or 240 to 240 VAC?  Also, why tie the AC around the bridge rectifier to the capacitors? V31joepalooka
