Title: Soft-switched full-bridge converters
Inventor: JANG YUNGTAEK
IPC: H02M3/335
Filed: 2002-03-01
Granted: 2003-10-01
Abstract: A family of soft-switched, full-bridge pulse-width-modulated (FB PWM) converters provides zero-voltage-switching (ZVS) conditions for the turn-on of the bridge switches over a wide range of input voltage and output load. The FB PWM converters of this family achieve ZVS with the minimum duty cycle loss and circulating current, which optimizes the conversion efficiency. The ZVS of the primary switches is achieved by employing two magnetic components whose vok-second products change in the opposite directions with a change in phase shift between the two bridge legs. One magnetic component always operates as a transformer, where the other magnetic component can either be a coupled inductor, or uncoupled (single-winding) inductor. The transformer is used to provide isolated output(s), whereas the inductor is used to store the energy for ZVS.

Abstract: The invention includes the reflection faces (2, 3) and the diaphragm (1), which is disposed between the reflection face (2) near the object side and the object for limiting light beam. At least one face of plural reflection faces (2, 3) is with non-axial symmetrical shape, and the reflection faces (2, 3) are disposed in a core-deviated way. The invention includes the light-blocking mechanism (6) for blocking light beam which is emitted from the outside of the object to pass through the diaphragm (1), which is not reflected by plural reflection faces (2, 3), and which is capable of reaching photographing range on the picture face (4). By disposing the light-blocking mechanism (6), the light beam that is not required will not directly reach the picture face. In addition, because there is no transmission face having refraction, the phenomenon of having non-required light which is not reflected by the transmission face to reach the picture face will not occur.
