“…The DC link section has a passive filter of LC filter 𝐿 1 and 𝐶 1 that plays a significant role in the ripple reduction (Musarrat et al, 2021;Ramakrishnan and Ravi, 2022). The 𝐶 1 capacitor acts as a bank of energy storage and supports suppressing ripple from the load.…”

A two-stage inverter (TSI) produces high second-order ripples in the low DC battery voltage operation, which cannot be used in telecommunication applications. Furthermore, it reduces the battery's performance and lifespan. This work analyses dual closed-loop feedback in a push-pull converter for eliminating second-order harmonics at the input of a TSI inverter system. During the discharge of a battery, its voltage decreases while the DC-DC converter's pulse width modulation duty cycle approaches its maximum value. This creates an open loop in the existing closed-loop scheme that returns the secondorder ripple at the battery input current. Introducing a battery voltage compensation stage in the existing system helps sustain the closed loop at a minimum operating voltage of the converter and maintains acceptable ripple levels. The proposed technique provides a viable solution for keeping the second-order ripple level at the entire operating range of the TSI inverter, even when the battery voltage decreases during discharge. Using the PSIM simulation tool, the proposed solution was validated in a push-pull converter, and the percentage of battery input current ripple was compared with the existing and proposed closed-loop control strategy. Finally, an 800 W/ 1 KVA prototype is built and tested, and the experimental results show that the proposed control techniques work to reduce ripples. The proposed control strategy has reduced the ripples from 10.2% to 1.4% at minimum operating voltage.

“…Also, power quality indicators correction is possible by inverter control. Shunt active power filter (APF) can be a proper choice for voltage and current harmonic compensation in the output of renewable DGs [3]− [5]. The APF can simultaneously solve the problem of the harmonics and lack of the reactive power [6].…”

<span lang="EN-US">In this paper, a novel current controller for selective compensation with active power filter (APF) in a microgrid (MG) is proposed. Power generation with sinusoidal voltage and high quality is essential in the microgrid. Hence, a current control-based method for shunt active power filters aiming to compensate the selective harmonic is proposed. Also, voltage source converter is used in the APF to improve MG power quality. Using the suggested control method can reduce total harmonic distortion (THD). The obtained results from the MATLAB simulations proved the superior of our method than other methods to decrease the current harmonic in a microgrid to an admissible area. Additionally, the practical results obtained from the implementation of the proposed control approach on an actual microgrid confirm the efficacy of the proposed method.</span>
