Title:
ELECTRIC-ENERGY CONVERTING APPARATUS FOR HEATING CYLINDRICAL SEMICONDUCTOR MATERIAL CONDUCTION-WISE
Document Type and Number:
Japanese Patent JP2010011729
Kind Code:
A
Abstract:

To provide a poly-phase circuit apparatus having no defect pointed out in conventional arts.

The three-phase rectifying apparatus 9 includes three heating circuits which are constituted out of a three-phase primary winding 2 connected with a feeding power supply, three secondary windings 3, 4, 5, and semiconductor materials 8 heated by the secondary windings 3, 4, 5. Each of the three secondary windings 3, 4, 5 of the transformer of the apparatus has more than two voltage taps 6 and power controllers connected in series with the voltage taps 6. Each voltage tap 6 is connected with each switching element 7 directly electrically on the side opposed to the transformer. The three heating circuits are connected with each other by a star connection in order to control their heat energies individually by load resistances 8. The power components of the power controllers are disposed so as to contact them with the three-phase transformer place-wise, in order to optimize the volume of the apparatus 9.
