Teardown: Leviton ground fault circuit interrupter
GFCIs detect hazardous current paths to ground and ground-to-neutral faults. A teardown reveals they are relatively simple but have circuit details that can be tricky to figure out. Bathrooms, kitchens, and other rooms with access to water are required to employ ac outlets with ground-fault circuit protection. GFCIs disconnect the output if they sense a […]
Wireless charging products to incorporate Qi- and PMA-compliant controller
ON Semiconductor has announced a strategic collaboration with ConvenientPower Systems (CPS) whereby CPS will design, develop and market in-vehicle wireless charging solutions using ON Semiconductor’s NCV6500 application dedicated, power management controller. The combined initiative is based around a single architecture that is scalable for multiple devices and coils to 15 W. A novel and patented technique for […]
Top power electronics stories of 2017
Here are the power electronics features that got the most interest from readers in 2017. Teardown: Inside Ikea’s smart LED bulb As smart LED bulbs go, this one is pretty simple. It doesn’t incorporate any sort of smartphone app and can’t be controlled over the Internet, like some other smart bulbs […]
Webinar: Automotive Imaging and the Semi-Autonomous / Autonomous Vehicle – November 28
Tuesday, November 28, 2017 2:00pm EST / 11:00am PST As automotive technologies advance, so do the number and complexity of electronically controlled “safety critical” functions inside of a car. Automotive imaging and viewing applications become critical to designs for next generation vehicles to enable new technologies and new solutions and to ensure rigorous […]
Six considerations for better circuit protection
In an electronic system where the power source can be connected the wrong way round, protection should be considered to prevent damage to the circuitry. Most electronic circuits don’t like the power supply being reversed. However, there are other eventualities you could protect your circuit or system from temperature, humidity, excess current or excess loading, […]

Power MOSFET forensics – I need your help to investigate a recent MOSFET death. It was […]
Power factor and Power Factor Correction, Pt 2
Part 1 of this FAQ discussed power factor and the issues associated with power factors which are not unity, and briefly mentioned power factor correction (PFC). This FAQ explores PFC in more detail. Q: What is PFC? A: PFC is an adjustment of a load’s front-end “appearance” so it presents a resistive-like load to the […]
Not to be forgotten: the simple, bipolar SCRs and TRIACs
Thyristors or silicon controlled rectifiers (SCRs) and TRIACs are simple bipolar devices which probably get forgotten in this high-tech, CMOS, MOSFET, digital world. A thyristor is a PNPN bipolar device, compared to a normal bipolar transistor which will be PNP or NPN. A common way of explaining their operation is to visualize the thyristor as […]
