In high power applications, semiconductor power modules containing paralleled MOSFETs are often used to achieve high output currents. The current distribution between devices within a module is influenced by several factors such as component layout, minor defects due to manufacturing tolerances, and general devices degradation that occurs over time. This paper describes a method of balancing the current between paralleled MOSFETs by independently modulating each device's gate-to-source voltage and measuring the corresponding drain-to-source currents. To achieve this, a detailed simulation is created using MATLAB and Simulink. A reinforcement learning agent is implemented with the goal of adaptively balancing power module current as the components inside degrade over time.
