Delays in short-circuit protection triggers require careful selection of the magnetics and overcurrent threshold values to prevent component stress. In any off-line flyback converter design, it is ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

There are many circuits for low voltage regulators. For higher voltages, such as supplies for valve circuits, the situation is different. That’s why we decided to design this simple regulator that can ...

Circuit protection has proven useful, but meeting the increasingly sophisticated industrial and commercial requirements can be a challenge. An overload or short circuit in a fuse or mini circuit ...

Reviewing a typical protective device trip curve (click here to see Fig. 2), it can be divided into three regions. First is the “instantaneous region,” which is the region intended to interrupt ...

If you have an application in which a MOSFET is already used to switch a load, it is relatively easy to add short-circuit or overload protection. Here we make use of the internal resistance RDS(ON), ...
