Transformer driving network with primary current limiting means

摘要

A non-linear network is disclosed for use in a power processor (converter) for limiting transformer primary winding current during (switching) transitions of a transformer driving potential, the network employing a resistor for coupling a suitably limited current from the potential to the winding and a saturable reactor connected in parallel with the resistor, the reactor for bypassing the resistor except during (and until a suitable period after) transitions of the potential level.
