Special Issue Information

Dear Colleagues,

The rapid deployment of renewable energies coincides with the carbon neutrality mission recently set by a growing number of governments (e.g., E.U., U.K., U.S, and China). High expectations are placed on the power and energy industry, where expanding the exploration of renewable energy is perhaps the only viable path. The power conversion system is the basic component of any energy system. It transforms other forms of energy into electric power that energizes the modern power network. For example, the major types of renewable energies (i.e., wind and PV) are integrated into the power system through the power-electronic interface, which plays a central role in renewable power production. The architecture and control of such energy conversion systems significantly impact the performance of energy production and their successful integration. Many new types of power conversion systems (in terms of topology and control approach) have emerged in recent decades, and there is still a great deal of room for performance improvement in power conversion architectures, which could be achieved by employing advanced and state-of-the-art technologies for system design. This Special Issue intends to foster the latest research and demonstrate emerging topics in power conversion architectures for different kinds of power and energy systems.

Prospective authors are invited to submit original contributions or survey papers, in which experimental results based on laboratory-scale hardware are desired to support the proposed ideas, for review and publication in this Special Issue. Topics of interest include, but are not limited to:

  • New topologies for power electronic converters, including AC/DC, DC/DC, DC/AC, AC/AC, etc.
  • New modelling and control methods for power conversion systems.
  • Advanced modelling and control of power and renewable energy systems.
  • Model predictive control for power converters.
  • Auxiliary controls of power conversion systems for grid integration.

All manuscripts must be submitted through Manuscript Central at https://susy.mdpi.com/user/manuscripts/upload/. Submissions must be clearly marked on the Special Issue “Advances in Power Conversion Architectures” on the cover page. When uploading your paper, please select the manuscript type as “Special Issue”. Manuscripts submitted for the Special Issue will be reviewed separately and will be handled by the Guest Editorial Board listed below.

This article proposes an electrothermal averaged model of a half-bridge DC–DC converter containing a power module. This kind of model enables the computation of characteristics of DC–DC converters using DC analysis. The form of the elaborated model is presented. Both the electrical and thermal properties of the analyzed DC–DC converter are included in this model. This is the first averaged electrothermal model of a DC–DC converter which makes it possible to compute the junction temperature of all the semiconductor devices and magnetic components. The accuracy of the model was experimentally verified in a wide range of switching frequencies and output currents. Particularly, the influence of mutual thermal couplings between the transistors contained in the considered module on the characteristics of the converter and the junction temperature of the transistors is analyzed.

To achieve “high voltage, low current” in the induction heating power circuit, enhance the flexibility of component selection in the circuit, and improve the quality of the inverter’s output waveform, a new control strategy of a single-phase NPC three-level inverter with unipolar frequency-doubling SPWM method is proposed. With the series connection of IGBTs in a single-phase NPC three-level inverter, the voltage withstand requirement of IGBT is reduced by half. The middle four IGBTs are controlled using unipolar frequency-doubling SPWM, while the outer four IGBTs are turned on later and turned off earlier to address the neutral point voltage imbalance issue in the inverter. Simulation results show that, compared with the traditional bipolar SPWM-controlled single-phase full-bridge inverter, the DC-side input voltage of the inverter can be double, and the current flowing through the entire circuit can be halved under the same output power using the proposed method.
