Inventor: MUTO NOBUYOSHI
IPC: H02P27/08
Filed: 1988-07-19
Abstract: PURPOSE:To generate a gate signal with high precision under no restriction of high speeding-up of a treatment time following up a rotating flux command by finding a synthesized voltage vector from a flux command value, a speed command value and a sampling cycle. CONSTITUTION:A pretreatment means 10 inputs a flux command value phiR and a speed command value WR to find a rotating angle thetaS(n) of a flux vector related to the command from the speed command value WR and a sampling cycle. Further, the pretreatment means 10 finds a command flux vector phiS(n) in the present sampling from the rotating angle thetaS(n) thus formed and the above flux command value phiR. A voltage vector synthesization means 20 finds the difference vector of the present command flux vector from the command flux vector phiS(n-1) found in the last sampling. This difference vector is synthesized by means of a plurality of voltage unit vector to find a synthesized voltage vector. A PWM signal generation means 30 generates a gate signal of an inverter in accordance with this synthesized voltage vector.

Title: High voltage transformer
Inventor: GOSEBERG WALTER DIPL ING
IPC: H01F27/24
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To reduce a temperature raised in a transformer by employing non-metallic material, which has a thermal conductivity higher than that of plastic and adhesive and which causes almost no eddy currentless, as the material of a spacer. SOLUTION: Cooling air 11 is passed to the region of a spacer 5 in a coil bobbin 4 of a high temperature region to cool the region. At this time, by the funnel effect of an opening 10, the cooling air is supplied in an optimum manner from a position under a,print board 9 to surround an iron core 3. Further, the spacer 5 comprising a small ceramic plate is in direct contact with two end surfaces of iron core legs 6a and 7a. This causes an air flow at the lower iron core leg 7a. Further, the spacer 5 having a higher thermal, conductivity attains good thermal exchange between the two iron cores. Thus, the air gap causes effective heat diffusion, not only upward but also downward, from the center of the transformer.
