... Schottky diodes use a metal-semiconductor junction as opposed to the semiconductorsemiconductor junctions used in standard diodes. This configuration allows for lower forward bias voltage drops (0.15V - 0.45V vs. 0.5-0.7V) and faster switching times, making them ideal for power supply switching oper ...

Metadyne
A metadyne is a direct current electrical machine with two pairs of brushes. It can be used as an amplifier or rotary transformer. It is similar to a third brush dynamo but has additional regulator or ""variator"" windings. It is also similar to an amplidyne except that the latter has a compensating winding which fully counteracts the effect of the flux produced by the load current. The technical description is ""a cross-field direct current machine designed to utilize armature reaction"". A metadyne can convert a constant-voltage input into a constant-current, variable-voltage output.
