What is the inrush current How does it affect our equipment?
Inrush current is the instantaneous high input current drawn by a power supply or electrical equipment at turn-on. If not limited, the high currents can damage the equipment in addition to producing voltage dips in the supply line and causing malfunctioning of other equipment powered from the same supply.
What is inrush current in electrical?
Inrush current, also referred to as “locked rotor current,” is the excessive current flow experienced within a motor and its conductors during the first few moments following the energizing (switching on) of the motor.
How does a protection circuit limit the inrush current?
Some of the active devices are Soft Starters, voltage regulators, and DC/DC converters. These protections are used to protect the electrical as well as a mechanical system by limiting the instantaneous inrush current. The below-mentioned graph show the inrush current value with the protection circuit and without the protection circuit.
What are the different types of inrush circuit?
One is passive inrush current limiting, in this passive inrush current limiting protection device is used. Another one is active inrush current limiting, in this active bypass circuit is used.
How can I protect my computer from inrush current?
For the protection from inrush current you can use an active or passive device. Choosing the type of protection depends upon the frequency of the inrush current, performance, cost, and reliability.
How are NTC thermistors used for inrush current limiting?
It is called an inrush current, and without protection, it may destroy a semiconductor device or have a harmful effect on the service life of a smoothing capacitor. NTC thermistors are used as ICLs (inrush current limiters) to protect circuits of electrical and electronic devices against inrush currents easily and effectively.
