Abstrakt: Single-phase converters are commonly used in small and medium power supply systems, but their inherent 2ω-ripple power has a significant impact on system performance, including maximum power point fluctuations in photovoltaic systems, low-frequency light flicker in light-emitting diode lighting systems, and the efficiency and lifetime of fuel cell systems. In this paper, we review the single-phase converter topologies with 2ω-ripple suppress and provide a comprehensive summary and comparison of power decoupling topologies. Power decoupling topology can be divided into passive power decoupling topology (PPDT) and active power decoupling topology (APDT). Among them, the PPDT does not need to add switching devices and has simple structure and convenient control. However, due to the volume and life of the energy storage element, the application place is also limited. The APDT needs to add an active power buffer to suppress the 2ω-ripple power. According to the different working modes of the active power buffer switch, the APDT can be divided into independent APDT and dependent APDT. The former operates independently in the original converter, while the latter needs to share switching devices or energy storage elements with the original converter. This paper systematically summarizes the existing single-phase converter circuit topologies for suppressing 2ω-ripple and their development process, aiming to provide classification and comparison for researchers and engineers to select the circuit topologies suitable for their specific applications.
