Abstract:
A dc power converter having bipolar output and bi-directional reactive current transfer, comprising in combination:a modulator coupled to a direct current source, said modulator comprising at least two switching means for generating a waveform pulse;a primary winding of a transformer capacitively coupled to said modulator;at least two secondary windings of said transformer magnetically coupled to said primary winding of said transformer;wherein said at least two secondary windings are bifilar wound;a first synchronous rectifier coupled to a first secondary winding of said at least two secondary windings comprising:a first switching means for interrupting a current path connected in series with said first secondary winding; anda first capacitor coupled in series with said first switching means;a second synchronous rectifier coupled to a second secondary winding of said at least two secondary windings comprising:a second switching means for interrupting a current path connected in series with said second secondary winding; anda second capacitor coupled in series with said second switching means; andsaid first secondary winding coupled said second secondary winding such that an output voltage from said first synchronous rectifier is in electrical opposition to a second output voltage from said second synchronous rectifier.
