In inverter-based distributed generation (IBDG) and similar to the conventional third order LCL filter, the high order LLCL filter is difficult to stabilize, and may cause a resonance between the inverter and the grid. ...

Inverters are considered the orbit of research objectives for safe and reliable grid interface. Amongst the conventional inverters known as suitable candidates for gird connection in the last two decades, Z-source inverter ...

This paper presents a new three-phase dc-ac inverter based on the basic Cuk converter. The main feature of the proposed topology is the fact that the energy storage elements as inductors and capacitors values can be reduced ...

Solar photovoltaic (PV) energy has witnessed double-digit growth in the past decade. The penetration of PV systems as distributed generators in low-voltage grids has also seen significant attention. In addition, the need ...

Although voltage source inverters (VSIs) are the most common DC-AC grid-tied converters, current source inverters (CSIs) are considered to be promising candidate, thanks to their low THD voltages/currents and inherent ...

An additional DC-DC boost converter is used in conventional configuration of Flywheel Energy Storage System (FESS) to regulate the output voltage during flywheel low speeds. This paper presents a new FESS based on the boost ...

Wind energy is one of the fastest growing renewable energy sources. The increased penetration of wind power into the utility grid brings challenges such as voltage and frequency fluctuations, generator torque ripples, and ...

Transformer-less photovoltaic (PV) inverters are the major functional units of modern grid-connected PV energy production systems. In general, two power conversion stages are required when low-voltage unregulated photovoltaic ...

MOSFET transistors are continuously being an essential part of power electronic converters due to their low switching losses at high switching frequencies. However, the traditional power MOSFET suffers from a relatively ...

This paper proposes a recovery strategy for wind energy-fed voltage source converter high voltage DC transmission systems, capable of maintaining power balance between the AC and DC sides during different AC faults. This ...
