Special Issue Information

Dear Colleagues,

This Special Issue follows the publication of the first volume focusing on “Advanced Power Generation and Conversion Systems”.

Over the last few years, power generation has changed due the to national and international climate and sustainability targets, economical constraints, and the diffusion of distributed renewable energy sources.

In the present context, it is mandatory not only to identify available resources in the short term, but also to implement adequate planning, management, and control actions in order to satisfy energy needs in both the medium  and long term.

Techniques which are able to improve power generators’ performances while also guaranteeing grid stability, reliability, and resilience could constitute key solutions to current and future service continuity and emission reduction.

Furthermore, the adoption of advanced materials, conversion technologies, and devices could permit the decrease of losses in AC, DC, and hybrid AC/DC power system improvements.

The main aim of this Special Issue is to obtain a complete overview of advanced materials, devices, technologies, and control logics in terms of power generation and conversion systems.

Submissions of technical works are welcome, and particular attention is dedicated to experimentally validated case studies and developed prototypes and demonstrators. The purpose of this Issue consists of providing relevant information, facilitating sharing among academic and industrial stakeholders, and not neglecting social impacts and roles.

The topics of interest include, but are not limited to, the following:

  • H2-based generation;
  • On-shore and off-shore wind generation;
  • Hydropower;
  • Multi-vector generation;
  • Cogeneration;
  • Tri-generation;

Alongside the interleaved concept, the floating two-stage converter concept can be applied to increase the power of a converter. Two converters can be connected in parallel at the input and in series at the output. Using two non-inverting step-down converters with a limited duty cycle, the output voltage of the complete converter is the sum of the output voltages of the two stages reduced by the input voltage. The load current of each stage is equal to the load current of the complete converter. It is useful to build such a converter symmetrically. The converter is treated in the steady state, and large and small signal models are derived using one converter stage which is loaded with the output current of the complete converter in the case of a resistive load. The inrush is studied when the converter is applied to a stable input voltage. To avoid the inrush, a pre-stage is connected in front of the converter. The voltage and the current stress of the semiconductor components are investigated. The transfer functions are calculated and Bode plots are shown for an operating point. Full article

This paper presents a comparative analysis of interior permanent magnet synchronous motor (IPMSM) drives powered by symmetrical and asymmetrical cascaded H-bridge multilevel inverters. The asymmetric topology operates using multiple DC sources with different voltage values, generating a voltage waveform with more output voltage levels than its traditional counterpart, all while maintaining the same hardware configuration. The main goal is to demonstrate that asymmetrical multilevel inverters are a promising option for improving the performance of electric drives while maintaining cost-efficiency and reliability. The proposed comparison is conducted through simulations in the MATLAB/Simulink R2024a environment, which allows an in-depth analysis of the dynamic performance of the electric drive. Additionally, the variation of the DC link input power of each H-bridge and the Total Harmonic Distortion (THD) of the voltage and current of the output of the converters were studied for different operating conditions in both cases. The obtained results were confirmed through real-time validation, demonstrating the applicability of electric drives powered by asymmetric converters and the advantages, in terms of efficiency, harmonic content and dynamic performance, in certain conditions of operation in terms of speed and applied load.

In a tristate converter the basic circuit topology is extended by an additional electronic switch and an additional diode. Three modes follow each other within one switching period. During the first mode M1, both electronic switches are on and both diodes are off. In the second mode M2, only the second switch is on and the first diode is conducting, and in mode M3, only the second diode is conducting. The voltage transformation ratio is a function of the two duty cycles of the electronic switches. In a typical tristate converter, the current flows through the second switch during the first two modes. In the converters treated here, the current is flowing through the second switch only during the second mode, so the losses are reduced compared to the normal tristate converter. This is shown for the Buck, the Buck–Boost, the Boost, the Zeta, the Cuk, the Super Boost, the quadratic Buck, and a reduced-duty cycle converter. The voltage transformation ratios are depicted in diagrams. As an example the reduced loss tristate Buck is used to demonstrate the derivation of the large and the small signal models. The transfer functions are also calculated and Bode plots are shown for an operating point. The voltage and the current stress of the converters are analyzed and the results are summarized in tables. The considerations are proved by simulations with the help of LTSpice. Full article
