Document Type and Number:
Japanese Patent JP6954239
Kind Code:
B2
Abstract:
A power converter may include first and second switching elements connected in parallel each other, first and second diodes connected to positive terminals of the switching elements, first and second current sensors, a reactor, and a controller that alternately turns on the first and second switching elements. One end of the reactor may be connected to first and second intermediate points. The first and second current sensors may detect currents flowing between the reactor and the first intermediate point and between the reactor and the second intermediate point, respectively. The first and second current sensors may respectively include first and second magnetism collecting ring cores, into which a first conductor between the reactor and the first intermediate point and a second conductor between the reactor and the second intermediate point are respectively inserted.
