Abstract EN
Opt coupler is a coupling component used commonly in feedback control loop circuits for power supply equipment.
Its high failure risk causes in most causes the breakdown of the whole equipment.
In this work, the wear-out process of this component is studied and a special attention to the most significant parameters variation is paid.
Different types of accelerated endurance tests under high temperature; high current and other types are applied to some batches of Opt coupler samples in order to determine the best fault signature of the components.
An accurate analytical model for the ageing of Opt couplers is proposed.
This model is based on microscopic analysis of physical phenomena at the semiconductor part of the component.
Finally, results obtained with the proposed model are compared to experimental results.
Thus the model can be used to optimize working conditions of Opt coupler and improve their lifetime and as a result the reliability of the whole power supply.
