Convertitore buckboost Wikipedia

Convertitore buck (riduttore o stepdown) seguito da convertitore boost (elevatore o stepup): la tensione di uscita è della stessa polarità dell'ingresso, e può essere maggiore o minore in valore. Questo tipo di buckboost non invertente può impiegare un singolo induttore utilizzato sia come induttore del buck e come induttore del boost.

Isolated nonisolated DCDC converters | EDN

An isolated DCDC converter will have a high frequency transformer providing that barrier. This barrier can withstand anything from a few hundred volts to several thousand volts, as is required for medical application. A second advantage of an isolated converter is that the output can be configured to be either positive or negative.
