Title:
POWER CONVERSION DEVICE
Document Type and Number:
Japanese Patent JP2015220953
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a power conversion device capable of suppressing a common mode current which flows outside.SOLUTION: A switching power supply 10 includes a first capacitor pair 34, a second capacitor pair 38, a bypass route 36 and a common mode choke coil 14. The first capacitor pair 34 is disposed between the output side of a full-wave rectifier circuit 18 and output terminals Tpout, Tnout. The second capacitor pair 38 is disposed between input terminals Tpin, Tnin and the input side of a booster circuit 16. The common mode choke coil 14 is disposed between the input terminals Tpin, Tnin, and the second capacitor pair 38. The neutral points of each capacitor pair 34, 38 are connected through the bypass route 36.
