POWER CONVERSION APPARATUS

摘要

Disclosed is a power conversion apparatus with further reduced inductance of conductors coupling condensers. The power conversion apparatus includes a smoothing circuit having first and second electrolytic condensers connected to each other in series and third and fourth electrolytic condensers connected to each other in series. The distance between a positive terminal of the first electrolytic condenser and a negative terminal of the third electrolytic condenser is shorter than the distance between the positive terminal of the first electrolytic condenser and a positive terminal of the fourth electrolytic condenser. The distance between the positive terminal of the fourth electrolytic condenser and a negative terminal of the second electrolytic condenser is shorter than the distance between the positive terminal of the fourth electrolytic condenser and the positive terminal of the first electrolytic condenser.
