Nokia Bell Labs’ Post

The #InterOPERA hardware setup at TU Delft | Electrical Engineering, Mathematics and Computer Science in the Netherlands is growing! A few days ago, Siemens Energy installed the Control and Protection equipment for its bipolar AC/DC converter station.   💪Thanks to the support from the local lab team, the system was fully operational after only 2.5 days - including the verification of bipolar STATCOM mode.     As soon as the replicas of the other HVDC vendors are in place, the official dry-run test will reach its next step.   Siemens Energy will now turn towards the second phase of InterOPERA starting the engineering of project specific demonstrator models

Based on early encounters with electricity in his childhood, Engineering professor Fang Peng made it his mission to study it. In a study published in Scientific Reports, he shows how a semiconductor device he created, named a Z-source inverter, can rapidly reduce voltage and current in the case of a short-circuit or open-circuit fault. Detecting short circuits faster than existing methods, Peng’s solution can be used to retrofit existing infrastructure to make it safer. "It is time to remake our grids and ‘tame the beast’ with power electronics." Read more: https://bit.ly/3xpaXV8 #electricalengineering #engineering #stem

⚡Day 5 of My 100-Day Power Electronics Challenge: Understanding SMPS Topologies Welcome back! Today, let’s explore the fundamental topologies used in SMPS (Switched-Mode Power Supplies). These topologies form the backbone of efficient power conversion, helping us achieve regulated output voltages for various applications. 🔆What is an SMPS Topology? An SMPS topology defines how power is converted from input to output using switches, inductors, capacitors, and transformers. The choice of topology depends on the required voltage conversion, power level, and application. Key SMPS Topologies 1. Buck Converter (Step-Down): Converts a higher input voltage to a lower output voltage. Common in devices like phone chargers and LED drivers. 2. Boost Converter (Step-Up): Converts a lower input voltage to a higher output voltage. Widely used in applications like battery-powered devices and solar inverters. 3. Flyback Converter: Suitable for low-to-medium power levels. Provides isolation using a transformer, making it ideal for adapters and small power supplies. 4. Forward Converter: Similar to the flyback converter but supports higher power levels with better efficiency. Used in industrial and telecom power supplies. ⚫How to Choose the Right Topology? 🔆For Low Power: Flyback is often preferred due to its simplicity and cost-effectiveness. 🔆For High Power: Forward or full-bridge converters are better suited. 🔆For Voltage Step-Down: Buck converters are the go-to choice. 🔆For Voltage Step-Up: Boost converters are ideal. 🔆Fun Fact for Today: The flyback converter originated from early TV designs, where it was used to generate high voltages for cathode-ray tubes! ⚫Tomorrow’s Topic: Stay tuned as I dive into the importance of feedback loops in SMPS design and how they ensure stability and regulation. 🤔Let’s Discuss! What SMPS topologies have you worked with, and what challenges did you face during implementation? Share your thoughts below! #PowerElectronics #SMPS #Engineering #100DayChallenge

"A study led by Dr. Haitham Kanakri and Dr. Euzeli Dos Santos, Jr., has unveiled a novel capacitorless solid-state power filter (SSPF) for single-phase DC-AC converters. This innovative technology employs a high-frequency planar transformer to eliminate the need for both LC filters and dc-link capacitors. Operating at 30 kHz, the H-bridge converter injects voltage harmonics to generate a sinusoidal output voltage. The research is published in the journal CES Transactions on Electrical Machines and Systems. Theoretical analyses, simulations, and experiments conducted on a 60 Hz, 120 V system demonstrated an impressive total harmonic distortion of just 1.29%, meeting IEEE 519 standards. Additionally, the research reveals a significant reduction in three critical components, underscoring the SSPF's potential to enhance both the efficiency and reliability of power electronics systems." #dcacconverters
