Abstract

This paper proposes a deep reinforcement learning (DRL)-based approach for directly controlling the gate signals of switching devices to achieve voltage regulation in a buck converter. Unlike conventional control methods, the proposed method directly generates gate signals using a neural network trained through DRL, with the objective of achieving high control speed and flexibility while maintaining stability. Simulation results demonstrate that the proposed direct gate control (DGC) method achieves a faster transient response and stable output voltage regulation, outperforming traditional PWM-based control schemes. The DGC method also exhibits strong robustness against parameter variations and sensor noise, indicating its suitability for practical power electronics applications. The effectiveness of the proposed approach is validated via simulation.
