Title: Inverter device linked to system
Inventor: WATANABE YOSHITOSHI
IPC: H02J3/38
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To enable growth into high speed and large capacity by arranging the constitution such that the primary winding of a transformer is connected between a power source and an irsverter, and that a separate inverter is connected in series to the secondary winding. SOLUTION: The main circuit of a device 14 is linked through a matching transformer 4 to the system, being made one inverter linked to the system, with an inverter 11 connected through a transformer 12 between a power source 1 and an inverter 3. Then, the inverter 11 gets the deviation between the compensating current commands Iru, Irv, and Irw and the outputs Icu, Icv, and Icw of an inverter current detector 5 from a subtracter 15, and further a comparator 17 increases it K2 times to get the voltage commands Vcu, Vcv, and Vcw to negate the components of higher harmonic waves of the inverter 3 and the operation delay.  Next, a triangular wave carrier generator 19 generates triangular wave carrier, and a subtracter 21 performs subtraction, and a comparator 23 performs comparison, thus the voltage to compensate the components of higher harmonic waves and the operation delay of the inverter is generated in the transformer 12 by controlling it by the on/off control signal. As a result, the reduction of higher harmonic waves and the high-speed following to the disturbance of the system materialize, whereby the growth into high speed and large capacity becomes possible.

Number of alumina base inclusion in the cast slab is reduced to 70% of the inclusion in the case of no blowing of the gaseous argon. Therefore, the alumina base inclusion in the molten steel in the tundish is effectively floated up and removed, and the continuously cast slab having excellent quality can be produced.
