Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

[Mark Rehorst] tells us about a tragic incident involving an untimely demise of $200 worth of motor driving hardware, and shares a simple circuit so that we can prevent such tragedies in the future.

Overvoltage protection of AC power lines is a common practice, which encompasses a variety of protection circuit solutions. Most designs are cost-driven and tend to use only the bare minimum of ...

Adding components to provide circuit protection against internal and external mishaps is one of those thankless design jobs, similar to buying insurance. When it’s not needed, it seems like an added ...

Varistors, also called metal-oxide varistors (MOVs), are used to protect sensitive circuits from a variety of overvoltage conditions. Essentially, these voltage-dependent, nonlinear devices have ...

I will be talking about single-series (1sXp) cell configurations, for a simple reason – multiple-series configurations are not something I consider myself as having worked extensively with. The single ...

Protect your devices with effective surge protection and power outage safety tips. Learn practical electronics protection ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

When overloads and short circuits occur, there’s always a tradeoff between the power supply shutting down the entire 24 VDC supply and keeping load circuits that aren’t impacted by the failure ...
