Special Issue Information

Dear Colleagues,

We are inviting submissions to the Energies Special Issue on “Conversion and Generation from Renewable Energies”.

This Special Issue is focused on systems that can generate and supply electricity from renewable energies.

Renewable energies are becoming more and more popular because they can fulfill power and energy demands at the local level with zero emissions and reduced environmental impact. Many features, such as efficiency, miniaturization of power converters, and control strategies, are fundamental to address sustainability, climate, and energy supply challenges.

Scenarios considering distributed power generation based on renewables, storages, and smart systems are increasingly being studied to solve problems, such as the varying dynamics, nonlinearities, and uncertainties. Impacts, problems, and advantages of these scenarios must be properly determined with advanced simulations, experimental tests, and real case studies.

The architectures of these scenarios are possible through the progressive evolutions of generators (including storages), and power converters based on the development of new technologies and solutions. For this, many challenges must be faced.

For example, the use of wide bandgap (WBG) semiconductors, such as silicon carbide (SiC) and gallium nitride (GaN), to produce power devices is revolutionizing power electronics converters. Due to their features, these devices are valuable for power converter efficiency, power density, reliability, and cost. Even if WBG devices have already been employed in some commercial and industrial products, further applications are expected soon. However, they still present design challenges (gate drive, gate protection, EMI suppression, converter controls, packaging, layout, power and signal integrity, etc.) arising from operation with high switching frequencies, high voltages, and high junction temperatures.

This Special Issue intends to report the latest progress in these important areas.

DC nanogrid architectures with Photovoltaic (PV) modules are expected to grow significantly in the next decades. Therefore, the integration of multi-port power converters and high-frequency isolation links are of increasing interest. The Triple Active Bridge (TAB) topology shows interesting advantages in terms of isolation, Zero Voltage Switching (ZVS) over wide load and input voltage ranges and high frequency operation capability. Thus, controlling PV modules is not an easy task due to the complexity and control stability of the system. In fact, the TAB power transfer function has many degrees of freedom, and the relationship between any of two ports is always dependent on the third one. In this paper we analyze the interfacing of photovoltaic arrays to the TAB with different solar conditions. A simple but effective control solution is proposed, which can be implemented through general purpose microcontrollers. The TAB is applied to an islanded DC nanogrid, which can be useful and readily implemented in locations where the utility grid is not available or reliable, and applications where isolation is required as for example More Electric Aircraft (MEA). Different conditions have been simulated and the control loops are proved for a reliable bus voltage control on the load side and a good maximum power point tracking (MPPT). Full article

Title: Electric vehicle traction train: energy conversion stages and DC bus capacitors

Affiliation: University of The Basque Country (UPV/EHU)
Abstract: International organizations and institutions consider the electrification of the transport sector a key factor in facing the environmental and energy challenges of the coming years. For electric vehicles (EVs) to be sustainable, they must meet a series of goals, set by various government agencies, in terms of power density, loss reduction, size, cost and reliability. For the latter, the lifetime of the components that make up the EV traction train is fundamental, the capacitors being critical elements of the EV's power converter stages, due to the number of failures they produce. For these reasons, this work analyzes the energy conversion stages used in the electric vehicle, as well as the technology of the EV traction train capacitors, especially that of the DC bus capacitor. Indicating its most critical parameters and the influence of operating conditions. All this, to get better performance from the capacitors, trying to reduce and avoid their main causes of rupture.
