I tried to simulate a circuit from MIT Power Electronics Lecture 2, and this is the simulation when it has reached periodic steady state. I added ground, original circuit didn't have one. Yellow line - v(vy, vz) - should be voltage across inductor L2. I know that the negative... Read more

I want to build something that include fans. Long story short, I am thinking of buying 8 computer case fans, 3d print a housing and install the case fans to create a specific airflow corridor. The DIY ...

Discover the latest enhancements in Simcenter Flux 2026.1, including accelerated electromagnetic simulations, improved modeling productivity, expanded engineering workflow connectivity and emerging approaches leveraging surrogate models and optimization.

For asset managers and equipment engineers, mastering Dissolved Gas Analysis (DGA) interpretation is essential, because gases like carbon monoxide and carbon dioxide are the first chemical signals that a transformer's solid cellulose insulation is overheating and degrading. Your transformer can talk, and if you know how to listen, you will hear it. Inside every oil‑filled power transformer, a sil…

Simcenter Fluxmotor 2026.1 introduces new capabilities for multiphase machine design, thermal-aware performance evaluation and enhanced connectivity across the Simcenter portfolio, helping engineers accelerate machine development from concept exploration to connected engineering workflows.

How do insulated-gate bipolar transistors (IGBT) (IGBTs) handle high currents despite the PNP region in its equivalent circuit being driven in active mode? My understanding is that active mode bipolar ...

I have a 3 phase star transformer circuit which is modeled in LTspice as below: I am using a 120V RMS, 60 Hz supply in each of three phases. Its peak value is 169.67V in each phase with a 120° phase ...

Ask someone to name the most important chip ever made and they will reach for a processor: an Intel CPU, an ARM core, maybe the microcontroller inside an Arduino. The real answer is humbler and far more widely produced. The best-selling integrated circuit in history is the 555 timer - an eight-pin part designed more than fifty years ago that is still manufactured by the billion every single year.…

Hello, I have tried to implement an open circuit microstrip resonator . I got the microstrip resonating at 5Ghz as shown below. However the S-parameters is very bad. Is there a way to improve the matching so It will have a better dip in 5GHz. ... Read more

Researchers from National Yang Ming Chiao Tung University (NYCU) and Chung Yuan Christian University have published “A Cross-Validated DSPN and Worst-Case Response-Time Framework for Timing Analysis of Automotive CAN Networks”. Abstract “Controller Area Network (CAN) remains a key in-vehicle communication protocol for distributed automotive control systems, where predictable communication timing …

Discover what’s new in Simcenter Feko 2026.1, with enhancements for large-scale electromagnetic simulation, antenna engineering, wireless system analysis and design exploration.

After building a CPU, utilities for handling bus interconnects, several DMAs and memory controllers, I often find my time focused on building interfaces between designs and external peripherals. This seems to be where most of the business has landed for me. Often, these peripherals require a clock output, coming from the design, and so I’d like to spend some time describing how to generate such a…

I would like to view 5-10 harmonics of a 3.3V 80MHz clock signal. I don't want to load the signal more than ~0.5mA. At first I thought I'd use a high-bandwidth op-amp like Texas Instruments ...

Please help me to identify SMD MOSFET transistor, that's have only "YJ" marking and small dots. Dots it's a "Time stamp of production", I think so. About MOSFET, yes I can be wrong ...

I've come across this circuit in a schematic at work. Unfortunately, the engineer that made it works somewhere else now. It appears to be a current limiting circuit for this optocoupler. When I ...

Verify FCC and CE certificates from Chinese suppliers, find accredited labs in Shenzhen, and write purchase orders that ensure you own the certification. Many Chinese factories will tell you their products are "FCC and CE certified." Some are correct. Some have real certificates for the version they showed you, not for the version they will ship you. Some have test reports — which are not the sam…
