Title:
TRANSFORMER MODULE, ELECTRICITY RECEPTION DEVICE, AND ELECTRICITY TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/122829
Kind Code:
A1
Abstract:
In the present invention, a circuit module (10A) provided with a primary coil, which is of a step-down transformer (13A) and results from the primary coils of a plurality of transformer elements (131, 132) being connected in series, and a secondary coil resulting from the secondary coils of the transformer elements (131, 132) being connected in series, is provided with: a printed substrate (17P) at which the transformer elements (131, 132) are arrayed and mounted in the lengthwise direction; a connection terminal (16A) to which the first end of the primary coil of the step-down transformer (13A) is connected; and connection terminals (16C, 16D) to which the secondary coil of the step-down transformer (13A) is connected. The connection terminal (16A) and connection terminals (16C, 16D) are provided to positions such that the transformer elements (131, 132) are interposed therebetween. As a result, provided are: a transformer module having a reduced effect of a high-voltage section on a low-voltage section by securing a distance between the high-voltage section and the low-voltage section; and an electricity reception device and electricity transmission device provided with the transformer module.
