Power supply products online search…easy or difficult?
As an electrical engineer, there are certain things that I look for when searching for a product online. It does not matter if the product is a component or power supply, the first thing I seek are specifications or data/technical sheets. I wondered how easy is it to find power product information. Inquisitively, I put […]
Complete Schematics, Inductor Designs and Bill of Materials Online
Power Supply WebDesigner (PSW) online tool is enhanced to include complete continuous conduction mode (CCM), non-isolated active PFC buck and buck LED driver designs. From user-specified design inputs, the tool allows designers to choose all the components used in a design or have the tool automatically recommend the design. This tool provides the inexperienced designer […]
Three common mistakes when designing power supplies
When I posed this question to companies that design power supplies, I thought that I was going to receive varying answers. Surprisingly, these companies tend to agree on the biggest mistakes that engineers/designers make in designing in-plant power supplies. For the purpose of this article , I have used specifications from a common ATX12V Power […]
Engineering and Concussion Reduction Therapy (CRT)
There has been a lot of discussion about aggressive sports and head injuries. These conversations are pertaining to the rising concerns of traumatic brain injuries resulting from forceful hits in contact sports. For males, football (US) is the most common sport causing concussions; while for females, soccer (US) is the most common sport. Over the […]
Update: Student loan forgiveness for Engineers
Don’t despair! We are getting close to a loan program that will help all engineers. Hold on to your hats kids. I went online to pay my student loan bill and observed that my loan service provider recently added the Public Service Loan Forgiveness program to its loan forgiveness list. What does this mean? This […]

Would you ride in a volocopter?
It’s a bird! No, it’s a plane. No, it’s a VOLOCOPTER! ….. What in the world is a volocopter? “The e-volo volocopter is a completely novel, vertical take-off and landing (VTOL) manned aircraft, which cannot be classified in any known category. The fact that it was conceived of as a purely electrically powered aircraft sets […]
Thyristor, Thyristor, How art thou thyristor?
A thyristor is like a diode; it can pass electricity in a forward direction but, blocks it in a reverse direction. The difference between a diode and a thyristor is that the thyristor is a three terminal device consisting of an anode, cathode and gate, which will also block current flow in the forward direction […]
8 ways electrical engineering is changing medicine
Electrical engineering (EE) is a field that goes beyond electricity and electrical components. In today’s world, EE’s are used frequently in the medical profession. Here are eight ways that EE’s are contributing to the medical field by developing products or software, and researching or working collaboratively with researchers in biomedical fields. 1.) Apps Doctors now […]
