Reliability Test Setup for Liquid Aluminum Electrolytic Capacitor Testing
Bus capacitors play a critical role in the operation of Variable Frequency Drives (VFDs) Failure of bus capacitors can cause a failure of the drive leading to unplanned downtime and substantial revenue loss for customers. In VFDs, liquid aluminum electrolytic capacitors are used as bus capacitors for smoothing of voltage and when line can't provide large bursts of energy (drive start up) and during temporary power loss. These liquid aluminum electrolytic capacitors are critical for the successful functioning of the VFDs for various customer applications. The VFDs are used across many industries such as paper, tire and rubber, oil and gas, and automotive. In order to select robust liquid aluminum electrolytic capacitors for the drives, reliability testing is critical.
