Dc-dc converter with a protection stage

Abstract

The invention relates to a DC to DC converter which comprises: (a) regulation stage for receiving a non-regulated DC voltage and for producing a regulated DC voltage; (b) a switching stage for converting said regulated DC voltage to a substantially AC Voltage signal; (e) an isolation stage for receiving said AC Voltage signal, and for producing a regulated output DC voltage having a voltage level which differs from a voltage level of said regulated DC voltage, and for isolating said regulated output DC voltage from said regulation stage; and (d) a control component for providing a feedback from said isolation to said regulation stage; wherein said DC to DC converter comprises at the regulation stage a protection unit which in turn comprises a capacitor in series with a parallel circuit which in turn comprises: a switching element in parallel with a resistor, inductor, or a controlled current limiting element.
