PHASE OVERLAPPED TYPE POWER SUPPLYING APPARATUS, CAPABLE OF REDUCING HIGH FREQUENCY NOISES BY APPLYING SINE-WAVE TO THE PRIMARY SIDE OF A POWER TRANSFORMER

摘要

PURPOSE: A phase overlapped type power supplying apparatus is provided to eliminate high frequency noises by fundamentally preventing the generation of high frequency peaking.;CONSTITUTION: A power inputting part(100) supplies power to a circuit. A power transformer(200) is in connection with the power inputting part in order to amplify a voltage. A plurality of transistors(400) is in parallel connection with each other in order to apply power to the power transformer. A bias controlling shift(300) controls the base voltage and the emitter voltage of the transistors. The transistor are operated in biased states. The collector voltage phase of a transistor is applied to the primary side of the power transformer as a sine-wave.;COPYRIGHT KIPO 2011
