Chip capacitors destined for high reliability testing are often designed with an added margin of safety, namely maximization of the dielectric thickness, and tested extensively for electrical properties prior to burn-in (e.g., capacitance, dissipation factor, and insulation resistance).
The test was stopped and after capacitors cooled down to room temperature, the measurements were taken. Testing liquid aluminum electrolytic capacitors before using them in the final product can greatly reduce the probability of field failures. PowerFlex series of drives manufactured by Rockwell Automation.
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. Liquid aluminum electrolytic capacitors have long been considered as the weakest reliability component in power electronic systems.
To select robust liquid aluminum electrolytic capacitors, the capacitors were tested using this test setup at rated temperature, rated ripple current plus DC voltage bias. Electrical parameters for the capacitors like capacitance, ESR and leakage current were measured before starting the test.
Electrical parameters for the capacitors like capacitance, ESR and leakage current were measured before starting the test. These electrical parameters were monitored by measurement at regular intervals during the test. The test was stopped and after capacitors cooled down to room temperature, the measurements were taken.
Liquid aluminum electrolytic capacitors have long been considered as the weakest reliability component in power electronic systems. Primary failure mechanism observed is evaporation of liquid electrolyte leading to a decrease in capacitance and increase in equivalent series resistance (ESR) and eventually causing the failure of the capacitor.
