What does a power supply consist of? May 20 ,2019
The basic unit of the power supply are: transformers, rectifiers, filters and voltage regulator circuits. The power unit uses all other electronic equipment with DC voltage as input. Its function prevents data corruption due to power failure and low voltage. Rectifiers, and filters are the three mai...

What is a regulated power supply? May 16 ,2019
The regulated power supply is a built-in circuit. With the help of a rectifier, the AC(alternating current) is transformed to DC(direct current). It has the ability to provide a regulated voltage (or lower frequency current) for circuits or devices that must operate within a certain power limit. The...

How does a switching mode power supply work? May 15 ,2019
In theory, switching regulators of switching power supply are no stranger to people. When it is a black box with input and output terminals, the operation of the switching regulator is the same as that of the linear regulator. However, the difference is that the linear regulator regulates the contin...

What is use of SMPS? May 14 ,2019
A Switching Power Supply (SMPS) is a switching power supply circuit that turns a high frequency power driver on and off through a Switchgear, and a storage module that powered by the switching device when is in a non-switching state, such as an inductor or a capacitor. SMPS are highly efficient and ...

What is the switching frequency of a power supply? May 13 ,2019
In Switched Mode Power Supply , which is adjusted by setting the minimum duration of DCM operation, the SMPS selectively operates in continuous current mode (CCM) and discontinuous current mode (DCM) with a minimum switching frequency. The resistance value applied to the external pin of the SMPS is ...

What is the difference between regulated and unregulated voltage? Apr 30 ,2019
Typically, the power supply is any device that provides energy to the LED drive circuitry. "Power" refers to a circuit or device that adjusts the available power based on the specific needs of a single device or a group of similar devices. In most non-industrial settings, the available power or inpu...
