Active Thermal Control of AC/DC Power Converter Considering Health Monitoring of Power Modules

The evolution of power electronics devices in the semiconductor sector has created a strong need for power modules that have high efficiency and low power usage. The power package; which embraces a couple of power electronics devices such as switches and diodes; provides mechanical supports, electrical interface, protection, and thermal management to the power electronics devices. The power package is power dissipation, resulting in a significant challenge to its thermal management. To lower the expenses on wasted power and minimize the need for cooling systems, it is imperative for power converters and their control algorithm to offer exceptional efficiency in converting power. Hence, efficient thermal control and sophisticated thermal design are crucial in developing the power module. In this paper, health monitoring of the power modules is considered in the active thermal control of a two-level power rectifier using a sequence-based model predictive control method. This paper sets the stage for monitoring the thermal response and health of power electronics devices by early diagnosis of degradation. This declines the thermal stress and makes a prompt prediction of failure. This would enhance the reliability of the power converter.
