Document Type and Number:
Japanese Patent JP6836243
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To increase a power transmission efficiency when performing wireless electric power transmission.SOLUTION: A power conversion device 1 according to the present invention comprises: a boosting DC-DC converter 11 connected between a battery 2 and a primary side DC capacitor 12; a primary side single phase inverter 13 connected between the primary side DC capacitor 12 and a primary resonance circuit 14; a secondary side single phase inverter 24 connected between a secondary resonance circuit 21 and a secondary side DC capacitor 25; a three-phase inverter 26 connected between the secondary side DC capacitor 25 and an electric motor 3; a boosting DC-DC converter 35 connected between the secondary side DC capacitor 25 and a capacitor 37; and a secondary side microcomputer 43 for controlling the boosting DC-DC converter 35 so that a current Ic such that a voltage E2 follows a voltage command E2flows through the capacitor 37.SELECTED DRAWING: Figure 1
