What is a LED driver used for? May 28 ,2019
Due to the increased use of energy regulations, most people are now familiar with the life and energy savings associated with LEDs or light-emitting diodes. However, many people do not know that these light sources require a special device to operate, that is, the LED driver. LED drivers (also known...

What causes the different colors in LEDs? May 24 ,2019
The working principle of LEDs is based on photon emission. The light emitting diode is essentially two oppositely doped semiconductors that are joined together to form a p-n junction. Doped semiconductors are used to enhance their conductivity. LED power supply can be done in two ways:The introducti...

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 ...
