This research introduces a cost-effective converter for single-phase machines, aiming to enhance efficiency and reduce energy consumption in retrofit applications. Single-phase motors commonly found in household appliances often suffer from low efficiency, resulting in wasted energy. To tackle this problem, a dedicated converter was proposed to replace the existing capacitors and improve the motor performance. This study presents a proof of concept for retrofit applications, discussing the converter design methodology and prototype evaluation. Additionally, a cost analysis comparing single-phase and three-phase motors is included. It aims to demonstrate the long-term cost savings and improved energy efficiency of the proposed converter. The findings highlight the converter’s potential as a promising solution for enhancing energy efficiency and decreasing costs in single-phase motor applications.

This work describes the development of a multiphase inverter that can operate as a platform for driving and testing electrical machines with up to 15 phases, in addition, it can operate with a fundamental frequency of up to 1 kHz and a switching frequency of 100 kHz. Therefore, a multiphase voltage source inverter (VSI) topology using SiC MOSFETs and approved components for automotive applications was designed and constructed. The developed platform is composed of independent power modules and a control module with technology that uses only a single microcontroller capable of generating all signals with pulse width modulation (PWM). To validate the inverter, experimental tests were carried out with a YASA (Yokeless and Segmented Armature) machine that can operate with 3, 5, or 15 phases and also with multistar connections, one with three independent systems of five phases and another with five independent three-phase systems. Experimental results show that the inverter is capable of driving and testing multiphase machines with a wide variety of electrical connections using high fundamental and carrier frequencies. Therefore, the developed platform is an important tool that allows the testing of multiphase and multi-star electrical machines operating under the most diverse configurations and operating conditions.

Power electronics is continuing its advance at a rapid pace [1], [2]. This is reflected in many emerging and re-emerging fields, such as wide-bandgap devices, device lifetime and reliability, high-density packaging, half-resonance and multilevel power conversion, machine-drive cooptimization, event-driven ultrafast and robust simulations, wireless power transfer, transportation electrification, structured dc, ac, or hybrid microgrids, electronic power grids, autonomous systems, and artificial-intelligence-enabled power systems [3], [4].IEEE JOURNAL OF EMERGING AND SELECTED TOPICS IN POWER ELECTRONICS (JESTPE) has been providing an effective vehicle for all our colleagues to share their most recent progress and address the toughest challenges. JESTPE is celebrating its tenth anniversary in 2023. To observe the anniversary, the JESTPE Editorial Board has organized a Special Issue on the Future of Power Electronics: Components, Circuits and Systems. We provide a special forum for our colleagues to reflect on the progress that we have made in power electronics and contemplating its future, together with its challenges and potential roadblocks.We have received 146 manuscripts, out of which the editorial review process accepted 42 of them. We organized the accepted papers as in the following eight sections. Section 1 has six invited papers that provide an overview of emerging technological trends and current challenges that we are facing in power electronics. It begins with a review of the SiC power devices, its future trends and the challenges in power application. The second paper provides an overview of upcoming trends in wireless power transfer, predicting a paradigm shift in wireless power transfer and related technologies. The third paper address the powerful extension of the discretestate event-driven simulation technique for megawatt power system simulation and design with order-of-magnitude faster speed and virtually free of convergence issue, particularly for hardware-in-the-loop prototyping and testing. The fourth paper discusses power supplies for data centers, a hot topic recently. The fifth paper presents an in-depth discussion on the recent trend in ultra-high-power-density that can be obtained with Si switching devices and its ability to remain in switching at a relatively low frequency. The underlying principles of halfresonance technic and typical performance are also discussed. The sixth paper is a tutorial in nature for high-density power module packaging. Typical challenges and effective solutions are discussed in detail.The rest of the accepted papers are organized into the following sections: 2) wireless power transfer, 3) reliability and diagnostics, 4) power quality and utility applications, 5) renewable energy and grid integration, 6) discrete and
