Voltage surge and transient suppression in EV chargers
Anything powered by an external source of electricity needs to be protected from voltage transients and surges, as it is not a question of whether such hazards will occur, but rather how often they will occur (and of what severity they will be). As might be expected, there are internationally agreed-upon regulations for surge and... Read more »

Suppression of Transients in an Automotive Environment
The new automotive multilayer (AUML) transient voltage suppressor is a voltage dependent, nonlinear device. It has an electrical behavior similar to that of a back-to-back zener diodes and it is inherently bidirectional. It offers protection from transients in both the
There are three basic types of failure modes: shorts, open, and degraded (outside of the specification limits). Although the silicon avalanche junction transient voltage suppressor (SAJTVS) will first fail short in most applications, there is always one transient event that …
10-103 Crowbar-type devices involve a switching action, either the breakdown of a gas between electrodes or the turn-on of a thyristor, for example. After switching on, they offer a very low impedance path which diverts the transient away from the parallel-connected

Battery Voltage: Understanding the Power Behind Your Devices
Batteries are an integral part of our daily lives, powering everything from smartphones to cars. At the heart of a battery''s ability to provide power is its voltage. Understanding battery voltage is not just a matter of technical knowledge; it''s essential for ensuring device compatibility, safety, and optimal performance.
How to Diagnose a Bad Car Battery – Practical Mechanic
A car battery voltage should be between 13.7 and 14.7 volts when the car is running, indicating that alternator is charging the battery and it can sustain the voltage. The following table gives some approximate voltages associated with …
Transient Voltage Surge Suppressors protect against transient voltage spikes that normally occur in less than one nanosecond (.000000001 second). The most common and inexpensive utilize one or more MOVs (Metal-Oxide Varistor). The effect of the MOV is to clamp the maximum voltage value at a specified level above the peak of the …
