Special Issue Information

Dear Colleagues,

The Topic Editors are inviting submissions for a Special Issue entitled “Status-of-the-Art Power Electronics Systems”. The semiconductor market is driving an exploding increase in demand for high-performance and reliable power systems. Providing enhanced electrical ratings in compact, cheap, easily manufactured, reliable, and thermal-aware designs is the current challenge that designers face in many application areas, such as energy distribution, automotive, aircraft, and spacecraft. Most of the academia and industry efforts are focused on power circuits (i) based on wide band-gap devices with enhanced electrical ratings, (ii) embedded in innovative and more reliable packaging technologies, (iii) supported by more efficient cooling systems, and (iv) benefiting from reduced electromagnetic interferences.

The scope of this Special Issue is to gather papers dealing with the analysis of electrical, thermal, and mechanical performances of state-of-the-art power electronics systems and with approaches to improve their reliability and mitigate detrimental effects induced by parasitics, thermal issues, solder delamination, and device failures. The manuscripts should be focused on—but not limited to—experimental characterization, modeling techniques (including model-order reduction), and low-resource-demanding, yet accurate, simulation methods where these topical issues are discussed.

We look forward to receiving your contributions.

The paper proposes a compact electrothermal model of the IGBT module in the form of a subcircuit for SPICE. This model simultaneously takes into account electrical phenomena occurring in the module components and thermal phenomena occurring in this module. In the description of electrical phenomena, the previously formulated models of the IGBT and the diode are used, whereas the description of thermal phenomena is original. While describing thermal phenomena, self-heating in each component, mutual thermal couplings between each pair of these components, and the influence of the dissipated power on the efficiency of heat removal are taken into account. The form of the proposed model and the results of its experimental verification for the IGBT module operating under different cooling conditions are presented. The DC characteristics of the module and the characteristics of the half-bridge converter containing the considered module are presented. Full article

This paper introduces a state-of-the-art inverter–machine codesign methodology for achieving an energy-efficient electric drive system. The methodology is applied in an optimal design case study with the context of the latest trend in the 800 V system. To reduce the voltage rating, a three-level active neutral point clamped topology is utilized in the inverter design, incorporating silicon carbide technology for high-speed operation. This combination allows for efficient power conversion with reduced losses. In the machine design, the increased number of poles that can be achieved in the design phase, along with the utilization of high-speed switching frequencies, enables the development of more efficient machines. Based on the design of the experiment method, by optimizing the parameters of both the inverter and machine simultaneously, using a cosimulation model, the 7.7% of total energy loss during drive cycle operation can be improved.

Enhanced class E inverters (EFn or E/Fn) reduce the high peak switch voltage that is prevalent in class E inverters. Additionally, their stability and load regulation capabilities are improved as compared to class E inverters. This paper proposes an enhanced class E inverter (E/F3) with a piezoelectric transformer (PT) replacing the auxiliary resonant networks. This class E/F3 inverter is designed by adding a tuned auxiliary LC network at the third harmonic of the switching frequency to the class E inverter. Both the primary and auxiliary resonant networks are realized using a piezoelectric transformer (PT). The converter is simulated in LTspice and an experimental prototype is built and tested. It is found that the experimental results concur with the simulation results, with a measured efficiency of 90%. Thus, the theoretical design is verified and the concept of energy extraction is achieved. Full article
