Title: Pfc converter
Inventor: JI HO KYUN
IPC: H02M3/28
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce harmonic current and improve the power factor of a converter, by varying the duty of a signal applied from a delay section to the gate of the switching element of a booster section, applied to a bulk capacitor according to increase or decrease in load voltage during switching. SOLUTION: A converter as a power supply is charged with input voltage V1 with harmonic current reduced in a bulk capacitor Cb by switching of the first switching element S1 in a booster section 32. Further, the stable voltage of the bulk capacitor Cb is applied to switching sections S placed upstream and downstream from a transformer section T. Thereby, power factor is improved. That is, in a two-phase controlled PFC (Power Factor improvement) converter comprising a PFC converter and a DC-DC converter, the turn-on time of the first switching element S1 is controlled to a given delay time through one control section 40, and the voltage of the bulk capacitor Cb is increased. As a result, two-phase control can be accomplished by single-phase control.

At this time, since the reflectance or the transmittance is changed by the film thickness of the polymer, the correlation between the reflectance or transmittance and the film thickness of the polymer is measured independently by a spectral guage for measuring a film thickness, etc. Therefore, only by measuring the reflectance or transmittance, the film thickness of the polymer can be measured accurately. Thereby, an accurate time for removing the polymer can be known.

Abstract: PURPOSE:To improve the deformability of allay powder at the time of hot forging, in Al-Si base alloy powder contg. specified amounts of Cu, Fe, Mg or the like, by specifying the amt. of Si and incorporating a specified amt. of Pb or Sn therein. CONSTITUTION:This hyper-eutectic Al-Si base alloy powder contains, by weight, 12 to 30% Si, 0.1 to 10% of one or more kinds among Cu, Fe, Mg, Ni, Mn and Ti, 0.2 to 2% Pb or Sn and the balance Al and has a structure in which Pb or Sn is dispersed into the grain boundaries and primary crystal Si is dispersed into the crystalline grains. In a green compact or a sintered body compacted by the above powder, because the state of the above Pb or Sn is formed into a liquid one at the time of hot forging, its deformation is made easy, so that it can show extremely high deformability. Thus, at the time of providing it with a complicated shape or thinness, cracks are not generated, and it can be compacted by low forging force. As for the content of Si, in the case its lower limit is <12, it uniformly disperses and distributes into the crystalline grains to improve the wear resistance of the obtd. member, and together with this, the desired effect can not be obtd. in the function of holding its thermal expansion coefficient to a low one.
