POWER CONVERTER

摘要

There is provided a power converter which can suppress a surge voltage and reduce noise flowing from an input of a power changer.;The power converter includes an inverter circuit 140, a capacitor 514 for smoothing DC power, a capacitor 515 for removing noise, and conductors 564p and 564n. The conductors 564p and 564n are connected to the capacitors 514 and 515 when power side terminals 562p and 562n are connected to an inverter circuit 140, and power source side terminals 561p and 561n are connected to a battery 136. In the conductors 564p and 564n, a parasitic inductance L1 between capacitor terminals 563p and 563n and capacitor terminals 560p and 560n is larger than a parasitic inductance L2 between capacitor terminals 563p and 563n and the power side terminals 562p and 562n.
