Power conversion apparatus

A power conversion apparatus comprising 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, wherein

• a positive terminal of the first electrolytic condenser and a positive terminal of the fourth electrolytic condenser are connected to a positive potential conductor,
• a negative terminal of the second electrolytic condenser and a negative terminal of the third electrolytic condenser are connected to a negative potential conductor,
• a negative terminal of the first electrolytic condenser and a positive terminal of the second electrolytic condenser are connected to a common potential conductor,
• a positive terminal of the third electrolytic condenser and a negative terminal of the fourth electrolytic condenser are connected to the common potential conductor,
• a distance between the positive terminal of the first electrolytic condenser and the negative terminal of the third electrolytic condenser is shorter than a distance between the positive terminal of the first electrolytic condenser and the positive terminal of the fourth electrolytic condenser, and
• a distance between the positive terminal of the fourth electrolytic condenser and the negative terminal of the second electrolytic condenser is shorter than a distance between the positive terminal of the fourth electrolytic condenser and the positive terminal of the first electrolytic condenser.
