Abstract: A cryptography method using a quantum phenomenon, which performs a multi-staged polarization process between a transmitter and a receiver to prevent a third party from knowing the polarization value of a photon. A transmitter rotates a photon flux by arbitrary angle ? and transmits it to a receiver. The receiver rotates the received photon flux by arbitrary angle ? and transmits it to the transmitter. The transmitter rotates the received photon flux by the reverse angle ?? of an angle, by which the transmitter 10 rotated it, then rotates it by polarization corresponding to an information bit, and transmits it to the receiver which rotates the received photon flux by the reverse angle ?? of an angle, and measures the polarization of the photon flux corresponding to the information bit, and recovers the information bit transmitted by the transmitter. Cryptography information may be transmitted using a plurality of photon fluxes.

Abstract: An improved soft switching topology of a full bridge PWM DC/DC converter is described. The new topology employs an energy recovery snubber to minimize a circulating current flowing through the transformer and switching devices. By using an energy recovery snubber instead of adding a tapped inductor and a saturable reactor to reduce RMS current stress, the converter achieves nearly zero current switching for the right leg of the full bridge circuit due to the minimized circulating current, and achieves zero voltage switching for the left leg of the full bridge circuit due to the reflected output current during the interval of left leg transition. The converter achieves soft switching for secondary side rectifier and freewheeling diode because at the turn-on time of the primary switching device, the energy recovery snubber provides a low impedance path.
