“…Equation ( 37) depicts the power loop duty ratio-to-inductor current transfer function in the buck-derived PPB, and Equation ( 39) the duty ratio-to-capacitor voltage transfer function. Further, Equations ( 38) and (40) show the phase angle expressions of the respective inner current/outer voltage loops.…”

“…Although the robustness of the control loop to transient disturbance and variation in LC values may be further improved by considering several nonlinear control methods in [38] which proposes an APD‐derived non‐linear control framework for the PPB by the way of state feedback linearization, which is extended further in [39] to introduce a Lyapunov‐based (LP) calculation for enhanced robustness, these methods applied to the PPB alone would cause a control computation time to exceed 2 µs. Similarly, the addition of an algebraic observer as proposed in [37] to remove the need for a Cb voltage sensor which additionally utilizes LP‐APD control laws and computations in [40] would further increase the control execution time. Therefore, due to the timing constraints of the digital control system imposed by the 100 kHz switching frequency, the proposed framework is an excellent choice as performance metrics are met.…”

This study provides a comparative analysis of feasible architectures of Power Pulsating Buffer (PPB) as an actively controlled energy storage solution alternative to the electrolytic capacitors in a single‐stage isolated, single‐phase 120 V AC 60Hz grid‐connected photovoltaic (PV) microinverter for a 400 W rated system with 20–40 V input range. The comparison encompasses key factors including energy density, volume reduction, efficiency, frequency operation, and system stability. The findings shed light on the primary advantages and disadvantages of the buck‐ and boost‐derived PPB under study. The results indicate that the boost PPB exhibits enhanced stability, a more compact design, and higher power efficiency compared to the buck PPB. However, for low switching frequency operations, the buck PPB proves to be more effective in mitigating DC port voltage ripple and ensuring controller over microinverter load variation.

“…According to whether the decoupling unit and the original converter switch are multiplexed or not, the active decoupling topology can be divided into dependent decoupling and independent decoupling. The independent decoupling circuit usually keeps working independently with the original converter [3][4][5][6][7][8][9][10][11][12]. However, independent decoupling usually requires more switching control capacitors or inductance compensation systems for double frequency power.…”

“…There is also an option to compensate for the double frequency in the form of a series H bridge in the system [4], 5. Literature [1][2][3][4][5][6][7][8][9][10] adopts the method of using a buck circuit as an independent decoupling unit on the DC side. In addition to using the basic circuit as an independent decoupling unit, literature [11], 12 adds a bridge arm on the DC side to control a group of split capacitor voltages to achieve the purpose of compensation.…”

Single-phase inverters have a wide range of applications in many fields, but there are inherent double frequency problems, and double frequency fluctuations can easily cause system instability. This paper proposes a mid-point common-mode injection power decoupling circuit. The advantage of this topology is that there are no additional switching devices and only the original DC side support capacitors and filter capacitors of the H-bridge inverter can be used to buffer the double frequency power. The half-bridge structure of this topology enables the AC side capacitors to operate positively and negatively, which can reduce the selection of the withstand voltage of the decoupling capacitor. Simulation and experimental results prove that the method can effectively suppress the secondary ripple on the DC side. The final data shows that the topology can effectively improve the system efficiency after decoupling.
