TL;DR: In this paper, an active capacitor converter (ACC) is adopted in place of the storage capacitor to improve the tracking ability of the terminal current of the ACC, a current reference feedforward control scheme is proposed, and it is further simplified for avoiding the use of the reciprocal and square root circuits.

TL;DR: In this article, a two-stage single-phase grid-connected photovoltaic (PV) inverter with active feedback active-damping (ADAD) was designed and a step-by-step closed-loop parameters design method was presented, and the experimental results verified the feasibility of the proposed control schemes.

TL;DR: In this paper, a front-end dc-dc converter with dc transformer (DCX)- LLC resonant converter is proposed to suppress the second harmonic current (SHC) in the front end.

TL;DR: A flying capacitor clamped (FCC) boost three-level (TL) converter is adopted, and the flying capacitor is employed to compensate the SHC for removing a large electrolytic capacitor, achieving a perfect SHC compensation performance.

TL;DR: A virtual impedance, which is in the form of a capacitor and a resistor connected in parallel, is introduced to be in parallel at the bus-side port of the SHCC for effectively compensating the SHC while guaranteeing the system stability.
