Title:
FILTER FOR ELECTRIC FIELD COUPLING PARALLEL RESONANCE TYPE POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2018183024
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a filter for parallel resonance type power supply system with high power transmission efficiency.SOLUTION: The filter for parallel resonance type power supply system includes a parallel resonance circuit at an input terminal and an output terminal. Between the input terminal and output terminal resonators, a band pass filter of a series three-element type BPF circuit is provided. A coupling capacitance is comprised of serial connection of two coupling capacitances and an inductor or a capacitance is provided between the terminal not connected to the input and output ends of the two coupling capacitances and the ground, thereby having a small coupling capacitance.SELECTED DRAWING: Figure 1
