Title:
POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/174722
Kind Code:
A1
Abstract:
A power transmission system comprises a power transmitting device (101) and a power receiving device (201). The power transmitting device (101) has: a power transmitting side active electrode (Eta) and a power transmitting side passive electrode (Etp); an inductor (L1) connected between the power transmitting side active electrode (Eta) and the power transmitting side passive electrode (Etp); and an AC generating source (SG) for applying an AC voltage between the power transmitting side passive electrode (Etp) and a reference electrode (Etg) to which a reference voltage level is assigned. The power receiving device (201) has: a power receiving side active electrode (Era) and a power receiving side passive electrode (Erp); and a load circuit (R) connected between the power receiving side active electrode (Era) and the power receiving side passive electrode (Erp). The power transmitting side active electrode (Eta) and the power receiving side active electrode (Era) are capacitively coupled to each other and the power transmitting side passive electrode (Etp) and the power receiving side passive electrode (Erp) are capacitively coupled to each other, thereby transmitting power from the power transmitting device (101) to the power receiving device (201). The coupling capacitance (Cag) formed between the power transmitting side active electrode (Eta) and the reference electrode (Etg) is set to be substantially equal to the coupling capacitance (Cpp) formed between the power transmitting side passive electrode (Etp) and the power receiving side passive electrode (Erp).
