97 100 874.3 YOKOGAWA ELECTRIC CORPORATION Patentansprüche97 100 874.3 YOKOGAWA ELECTRIC CORPORATION Patent claims 1. Transformator mit gedruckten Spulen, umfassend:1. Printed coil transformer comprising: ein Primärspulenmittel (10) mit einem Leitermuster, das einer Primärwicklung (nl) eines Transformators äquivalent ist,a primary coil means (10) having a conductor pattern equivalent to a primary winding (nl) of a transformer, ein Sekundärspulenmittel (20) mit einem Leitermuster, das einer Sekundärwicklung (n2) des Transformators äquivalent ist,a secondary coil means (20) having a conductor pattern equivalent to a secondary winding (n2) of the transformer, wobei die Primär- und Sekundärwicklungen mit unabhängigen (getrennten) Erden bzw. Massen verbunden sind und wobei die Transformatorpolarität(en) der Primär- und Sekundärwicklungen entgegengesetzt ist (sind), undwherein the primary and secondary windings are connected to independent (separate) earths and grounds, and wherein the transformer polarity(s) of the primary and secondary windings are opposite, and ein drittes Spulenmittel (72) mit einem Leitermuster, dessen eines Ende geerdet ist bzw. an Masse liegt und dessen Transformatorpolarität mit derjenigen der Sekundärwicklung übereinstimmt,a third coil means (72) having a conductor pattern having one end grounded and having a transformer polarity matching that of the secondary winding, wobei das dritte Spulenmittel (72) ferner eine Leiterwicklungsschicht aufweist, an welcher eine Spannung des Leitermusters am dritten Spulenmittel (72), die durch eine an die Primärwicklung angelegte Wechselspannung generiert ist, nahezu mit einer an der Sekundärwicklung generierten Spannung übereinstimmt.wherein the third coil means (72) further comprises a conductor winding layer at which a voltage of the conductor pattern on the third coil means (72) generated by an alternating voltage applied to the primary winding approximately coincides with a voltage generated at the secondary winding. 2. Transformator mit gedruckten Spulen, umfassend: ein Primärspulenmittel (10) mit einem Leitermuster, das einer Primärwicklung (nl) eines Transformators äquivalent ist, und2. A printed coil transformer comprising: a primary coil means (10) having a conductor pattern equivalent to a primary winding (nl) of a transformer, and ein Sekundärspulenmittel (20) mit einem Leitermuster, das einer Sekundärwicklung (n2) des Transformators äquivalent ist,a secondary coil means (20) having a conductor pattern equivalent to a secondary winding (n2) of the transformer, wobei die Primär- und Sekundärwicklungen an jeweiligen unabhängigen Wechselstrom-Massen (AC GND) geerdet bzw. an Masse gelegt sind und ihre Leitermuster in der Transformatorpolarität identisch sind, (und)wherein the primary and secondary windings are earthed to respective independent AC grounds (AC GND) and their conductor patterns are identical in transformer polarity, (and) die Sekundär- und Primärspulen so laminiert oder geschichtet sind, daß die Spannung über die Sekundärspulen-Leitermusterschicht an der der Primärspule gegenüberliegenden Ebene der Spannung über die Primärspulen-Leitermusterschicht an der der Sekundärspule gegenüberliegenden Ebene nahezu gleich ist.the secondary and primary coils are laminated or layered such that the voltage across the secondary coil conductor pattern layer at the plane opposite the primary coil is substantially equal to the voltage across the primary coil conductor pattern layer at the plane opposite the secondary coil. 3. Transformator mit gedruckten Spulen nach Anspruch 2, wobei das Sekundärspulenleitermuster an der der Primärspule gegenüberliegenden Ebene dem Prxmarspulenleitermuster an der der Sekundärspule gegenüberliegenden Ebene spiegelgleich ist.3. A printed coil transformer according to claim 2, wherein the secondary coil conductor pattern on the plane opposite the primary coil is a mirror image of the primary coil conductor pattern on the plane opposite the secondary coil.
