Title: Switching power supply device
Inventor: IMAGUCHI MAKOTO
IPC: H02M1/00
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a switching power supply device which is insulated between a primary side and a secondary side, less radiates switching noise into the air, and less transmits noise to its outside. SOLUTION: A radiating board 2 for radiating the heat of a main switching element Q1 is insulated electrically from a primary circuit, and connected to a secondary-side ground through a capacitor C4. As the result of this, radiation of switching noise into the air from the heat sink and transmission of noise to the outside of a power device decrease, since noise caused by switching of the main switching element Q1 is not transmitted directly to the heat sink. Furthermore, insulation distances from primary components are not required, and size reduction becomes easy, since the heat sink is insulated by the capacitor C4.

Abstract: PURPOSE:To realize an effective induced four-photon mixture (SFPM) over a long interaction length even at a low excitation input by a method wherein an excitation wavelength is set at a zero dispersion wavelength or its neighborhood of an optical fiber in order to reduce a group delay time difference among an excitation optical pulse, a Stokes optical pulse and an anti-Stokes optical pulse. CONSTITUTION:An excitation optical pulse row from an excitation light source 7 is coupled to a fiber 4 from an optical isolator 9 via a dichroic mirror 8 and a coupling lens 3. During this process, a wavelength of an excitation optical pulse is set in such a way that it nearly coincides with a zero dispersion wavelength of the optical fiber 4 constituting an optical-fiber resonator. As the excitation optical pulse is propagated inside the optical fiber 4, a Stokes beam and an anti-Stokes beam which are generated by a noise are begun to be formed. The Stokes beam and the anti-Stokes beam are soon amplified along the optical fiber 4, and an SFPM is generated. A group delay time difference among the excitation optical pulse, the Stokes beam and the anti-Stokes beam is small; accordingly, an effective interaction is generated over a long distance.
