Two-stage single-phase photovoltaic inverters exhibit a second-harmonic ripple at the dc-link voltage, which can cause variations in the terminal voltage of the photovoltaic array,
The cause of the secondary ripple and the mechanism of propagation was analyzed in this article.
This paper analyzes the mechanism of the secondary ripple generation and propagation of the two-stage single-phase inverter, and applies the model predictive control to
To mitigate the impact of ripple components on the converter, a DAB control strategy based on constant power transfer is proposed. Finally, a 300W prototype platform was constructed, and
In order to better suppress the secondary current ripple at the input side of the single-phase inverter, researchers have put forward
By transferring the double-frequency ripple in the DC-link capacitor of the inverter to another capacitor that has no connection to loads, it can suppress the low-frequency ripple
A dual-dc-port ac–dc converter-based structure is proposed to suppress the second-order ripple power in a single-phase ac–dc power system.
In order to better suppress the secondary current ripple at the input side of the single-phase inverter, researchers have put forward many solutions.
Aiming at this problem, this paper proposes a two-modal modulation method and its MPC multi-loop composite control strategy on the circuit topology of a single-stage boost inverter with a
By transferring the double-frequency ripple in the DC-link capacitor of the inverter to another capacitor that has no connection to loads, it can suppress the low-frequency ripple
The amplitude of the second-ripple component detected in real time is used for ripple suppression, while the DC component is used to isolate the impact of the output voltage
