Title:
パワーコンディショナおよびパワーコンディショナの故障箇所推定方法
Document Type and Number:
Japanese Patent JP7380244
Kind Code:
B2
Abstract:
To provide a power conditioner and a power conditioner failure point estimating method in which a failure point in the power conditioner can be estimated with high precision without requiring detection by a worker, detection of the rotation speed of a fan, detection of temperature, or the like.SOLUTION: A power conditioner including a switching element, and a cooling mechanism that cools the switching element, converts inputted DC power to AC power, and outputs the AC power. The power conditioner includes a monitoring unit that estimates a failure point on the basis of the outputted AC power.SELECTED DRAWING: Figure 1
