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, where Z1 represents an impedance of a first element, Z2 represents an impedance of a second element, Z3 represents an impedance of a series circuit formed by the capacitance (Ca) and a load, 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 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.
