Claim Text:
1. 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 the first and second electrolytic condensers and the third and fourth electrolytic condensers are arranged in an array of electrolytic condensers comprising n rows and m columns of electrolytic condensers, the first electrolytic condenser is arranged in a same row as the second electrolytic condenser among the n rows of the array and a same column as the third electrolytic condenser among the m columns of the array, 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 negative terminal of the second 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 negative terminal of the third electrolytic condenser.
