Title:
FILTER FOR ELECTRIC FIELD COUPLING PARALLEL RESONANCE TYPE POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2014155427
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a filter for a parallel resonance type power supply system with high power transmission efficiency.SOLUTION: A filter for a parallel resonance type power supply system is characterized in that, a C-coupling band-pass filter comprises parallel resonance circuits in an input terminal and an output terminal in a parallel resonance type power system, and the input terminal and output terminal resonators are connected by a coupling capacitor. The coupling capacitor is formed by connecting two coupling capacitors in series and an inductor or a capacitor is provided between a terminal which is not connected to input/output terminals of the two coupling capacitors, and a ground, thereby having small coupling capacitance. The filter for the parallel resonance type power supply system is also characterized by having a balanced configuration of the filter.
