Document Type and Number:
Japanese Patent JP5472547
Kind Code:
B2
Abstract:
A capacitance (Cp) is a capacitance formed between a transmitting-device-side passive electrode and a receiving-device-side passive electrode. A capacitance (Ca) is a capacitance formed between a transmitting-device-side active electrode and a receiving-device-side active electrode. A bridge circuit formed by Z1 to Z4 is connected to a secondary side of a step-up transformer (13T), where Z1 represents an impedance of a first element (16x), Z2 represents an impedance of a second element (16y), Z3 represents an impedance of a series circuit formed by the capacitance (Ca) and a load (RL), and Z4 represents an impedance of the capacitance (Cp). By determining the impedances Z1 to Z4 such that this bridge circuit is balanced, a potential at a receiving-device-side reference potential point (RG) is made equal to a ground potential. This reduces variation in receiving-device-side reference potential, reduces noise, and stabilizes the operation of a load circuit on the receiving device side.
