Active power decoupling methods are developed to deal with the inherent ripple power at
twice the grid frequency in single-phase systems generally by adding active switches and …

The relative share of renewable energy, specifically the solar photovoltaic (PV), is increasing
exponentially in the world electric energy sector. This is a cumulative result of reduction in …

Switched-capacitor-based multilevel inverters for boost-type dc–ac power conversions
usually exhibit a trade-off between the switch count and switch-voltage rating, ie, a reduction …

Single-phase ac/dc or dc/ac systems are inherently subject to the harmonic disturbance that
is caused by the well-known double-line frequency ripple power. This issue can be eased …

This paper presents a transformerless inverter topology, which is capable of simultaneously
solving leakage current and pulsating power issues in grid-connected photovoltaic (PV) …

The instantaneous input and output power of two-stage single-phase converter are
imbalanced, resulting in the second harmonic current (SHC) in the dc-dc converter, dc …

Galvanic isolation in grid-connected photovoltaic (PV) microinverters is a very important
feature concerning power quality and safety issues. However, high-frequency transformers …

A high-efficiency, high-power-density buffer architecture is proposed for power pulsation
decoupling in power conversion between dc and single-phase ac. We present an active …

Based on the hybrid operation of interleaved flyback micro-inverter in discontinuous and
boundary conduction modes (DCM and BCM), a novel adaptive snubber is proposed in this …

Capacitive dc-links are widely used in voltage source converters for power balance, voltage
ripple limitation, and short-term energy storage. A typical solution, which uses aluminum …
