In modern energy production, storage, transmission, distribution, and consumption, power electronics has been playing a crucial role. Because power converters are critical links in electrical energy systems, impacting system security, safety, energy efficiency, and cost, the reliability of power electronic components and converter systems has become very important in these applications. In short, the reliability of energy systems is completely dependent on the reliability of electronic components and power converters. Consequently, testing is now considered a vital reliability engineering tool to investigate failure mechanisms, identify weakest points, and demonstrate robustness margins in components and converters. However, reliability testing is not simple and requires time, right amount of data, state-of-the-art testing facilities, and understanding of uncertainties of failure mechanism.

- EV Battery Chargers, Inverters, Bidirectional Switches, and Passive Components Take Center Stage at ECCE 2022
This year, the fourteenth annual IEEE Energy Conversion Congress and Exposition (ECCE) 2022 was a hybrid event with an in-person meeting in Detroit, MI, USA from 9–13 October. The virtual meet-the-authors sessions took place 17-19 October via Zoom. After two years of virtual meetings, it was encouraging to see researchers, engineers, and professionals from around […] - A Proprietary ZVS-Based Approach Delivers High Efficiencies at Light Load With Half the Components of Conventional Designs
The ac–dc power supply units providing isolated, regulated outputs operating above 100 W typically require some form of input active power factor correction (PFC) [1] . To achieve this, a popular solution is to combine a boost PFC input stage with an “LLC” converter which isolates and controls the dc output voltage. However, a new, […] - Gate-Source Voltage Analysis for Switching Crosstalk Evaluation in SiC MOSFETs Half-Bridge Converters
Measuring the gate-source voltages of wide bandgap (WBG) devices in half-bridge converters provides useful information about susceptibility to crosstalk, which can cause uncontrolled cross-conduction and excessive gate-oxide stresses. However, parasitic elements of the printed circuit board (PCB) and device packaging can compromise measurement accuracy, causing unreliable results. Here we describe how this shortcoming can be […] - Smart Efficiencies Enable the Internet of Everything
In the next 10–15 years, power electronics will enable the Internet of Everything (IoE) to reach a trillion sensor economy. To achieve this high volume will require focus on data and system energy trade-off within a functional framework of Sense, Think (Compute), Act, and Communicate. The IoE session of the IEEE Future of Electronic Power […] - AI/ML and Cybersecurity in Power Electronics
Artificial intelligence and machine learning (AI/ML) have been applied to power electronics and electric drives research for more than 20 years for design, control, estimation, and prediction. With the recent interest in AI/ML for all aspects of smart and connected daily life, the interest in AI/ML applications of power electronics has also increased. With the […] - Brainstorming for Game-Changing Ideas
This year, the IEEE Future of Electronic Power Processing and Conversion (FEPPCON) XI held in Reykjavik, Iceland, 3–7 June 2022, added a new form of technical session called “Brainstorming for Game-Changing Ideas” through poster presentations and discussions, initiated by the late past president of IEEE Power Electronics Society (PELS) Braham Ferreira. The workshop participants were […] - FEPPCON XI: Powering Global Progress
In June 2022, the IEEE Power Electronics Society (PELS) held its eleventh biannual long-term strategic outlook meeting the Future of Electronic Power Processing and Conversion (FEPPCON XI) in Reykjavik, Iceland ( Figure 1 ). FEPPCON XI was postponed by one year from 2021 due to the global pandemic to allow a face-to-face meeting. Most invited […] - Application-Oriented Reliability Testing of Power Electronic Components and Converters
Power electronics have been and will continue to be an enabling technology for energy production, storage, transmission, distribution, and consumption. Power electronic converters are usually the critical links in electrical energy systems, affecting system security, safety, energy efficiency, and cost-of-ownership. As a result, the reliability requirements for power electronic components and converter systems generally become […]
