Abstract: A DC-DC converter apparatus comprising half or full bridge, two-stage resonant converter, which may include series resonant (inductor, capacitor) devices. An isolated transformer having primary and secondary winding supplies current to full-wave secondary stage-bridge through the use of primary winding resonant devices employing primary stage-bridge. The magnetizing of said devices employs zero-current, zero-voltage resonant-transition switching technology, which reduces switching losses at all switching frequencies to almost zero. The regulation of output voltage at all loads and input voltages achieved by the control of the switching frequency and the phase between signals for primary and secondary stages. The proper intermittent of the frequency and the phase allows achieving the value of efficiency up to 97%.
