Abstract
A DC converter with active clamping comprises a transformer having one secondary winding that is connected via a series connected diode to a filter capacitor, and another secondary winding that is coupled by the end thereof to the beginning of the first secondary winding and is connected via a series-connected diode to an input of an L-type LC filter, an output capacitor of which is connected in series to the aforesaid filter capacitor. The input of the L-type LC filter is connected via a bypass diode to the common connection point of the capacitors of the filters, and a load is connected in parallel to said capacitors. The technical result is a decrease in dynamic losses.
Claims3
A DC voltage converter with active clamping, comprising a transformer having a primary winding connected via a power switch to the terminals of a constant input voltage source, in parallel with which a clamping element consisting of a series-connected capacitor and an additional switch is connected, secondary windings with rectifier diodes connected to an LC filter, characterized in that the first secondary winding of the transformer is connected to the first filter capacitor through a series-connected diode, the second secondary winding of the transformer, connected at the end to the beginning of the first, is connected through a series-connected diode to the input of an LC filter, the output capacitor of which is connected in series with the first filter capacitor, and the input of the LC filter is connected through a shunt diode to a common connection point of the filter capacitors, in parallel to which the load is connected.
