Understanding the overcurrent trilogy will help you protect your circuits. Circuit overcurrent protection encompasses overload, short-circuit, and ground-fault protection. NEC Art. 100 defines ...

Most AC-DC power supplies and DC-DC converters have internal current-limiting circuits to protect the power device, and to some degree its load. The majority of over-current-protections include an ...

A monthly overview of things you need to know as an architect or aspiring architect. Unlock the full InfoQ experience by logging in! Stay updated with your favorite authors and topics, engage with ...

Insulated-gate bipolar transistors (IGBTs) require full protection to avoid damage and failures resulting from conditions such as short circuits, overloads and overvoltages. The protection is key to ...

Fuses and circuit breakers are located at the beginning of most circuits but at the end of a service. Could Art. 230 [Services] be an exception to Art. 240 [Overcurrent Protection], and are ...

Rectifiers and ac-dc power supplies employ large bulk capacitors. During power-up, these capacitors require a large amount of current to charge up, resulting in a large inrush current. This inrush ...

Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

The RSGD Series from Carlo Gavazzi is an easy to use soft-starter for 3-phase induction AC motors, needing just three settings. The self-learning algorithm adjusts the unit's parameters to work with ...
