| description | Active power decoupling (APD) technology demonstrates significant advantages in addressing the mismatched second-order ripple power issue in single-phase rectifiers. However, conventional methods typically require additional voltage or current sensors to achieve precise decoupling control, thereby increasing the cost of the decoupling circuit. To reduce costs and simplify the control system, a sensor-reduced decoupling control method is proposed, with its key advantages highlighted in three aspects: First, the proposed method operates by replacing actual sampled variables with designed reference values, reducing the number of sensors—only the DC bus voltage information is required for operation. Second, the sensor-reduced control scheme is designed based on Lyapunov stability conditions and ensures system stability. Third, virtual impedance produces the reference current of the decoupling circuit, which eliminates grid signal interaction and simplifies control. Simulation and experimental results validate the effectiveness and feasibility of the proposed method. |
