Title: Leakage transformer type stabilizer
Inventor: YOSHIDA SHIGEHISA
IPC: H01F38/08
Filed: 1987-01-23
Abstract: PURPOSE:To reduce vibration of an external iron core, by stacking iron core plates to form an iron core, and securing the plates with each other at a place of the outer iron core corresponding to the center of a secondary winding as viewed in the axial direction. CONSTITUTION:A polarization iron core 7 is pressure contacted with an external iron core 3 so as to inhibit vibration of the external iron core 3. In an internal iron core 2, a bridge cap 12 for reducing the width of magnetic path is provided at a place where a secondary winding 6 is wound, so that, when a lamp is lit, magnetic saturation causes magnetic leakage at said place. Further, core plates are welded with each other at a place 13 on the outer side face of the external iron core 3 approximately corresponding to the center of the secondary winding 6 as viewed in the axial direction. Thereby, vibration level and hence noise can be reduced substantially.

Abstract: PROBLEM TO BE SOLVED: To connect a plurality of inverters in series or in parallel to each other and detect ground leakage in the respective inverters easily. SOLUTION: Resistors R1-R4 are connected between the output terminals of inverter circuits 401 and 402 so as to form a bridge. Divided voltages of the respective middle points M1 and M2 are inputted to a differential amplifier 25. Particularly, the middle point M2 is connected also to an earth terminal E.
