In electric power processing converters for highprecision
voltage supply, usually correction amplifiers are connected
in series with a main low-accuracy power amplifier. As
such, conventional switched-mode correction amplifiers have also
to process the total current as delivered by the main amplifier.
Therefore, switching semiconductors with high current rating
have to be selected for implementing correction amplifiers. This
paper proposes a solution this problem by separating the major
part of the current delivered by the main amplifier from the
current part that flows through the switches in the correction
amplifiers. As a result, the switching semiconductors used in the
correction amplifiers have a much reduced current rating, and
the overall system efficiency can be increased.
