The conditions, composition, and precautions of LED switch power supply

Among the types of switch mode power supplies, LED switch mode power supplies are a very popular topic, and they are widely used in people's daily lives. Compared to other products such as waterproof switch power supplies, high-power switch power supplies, and industrial control switch power supplies, LED power supplies have some advantages on the network. Specific users need to be clear about the adoption of LED power supplies on the network. In the future development of the switch power supply industry, LED power supply will undoubtedly become a new highlight of the power supply industry. This article summarizes some basic knowledge of LED power supply.

Several conditions for LED switch power supply: 1. DC 2. High frequency 3. Switching.

The composition of LED power supply: Key electronic components include LED diodes, MOSFETs, and IGBTs. SCR is only used in small quantities in the input rectification circuit and soft start circuit of switching power supplies. GTR driving is more difficult and the switching frequency is also low, gradually being replaced by IGBT and MOSFET.

Therefore, I say this only because there are three points that must be noted:

One reason is that power electronic devices operate in a switching state rather than a linear state.

Secondly, power and electrical components operate at high frequencies rather than low frequencies.

Thirdly, the output of the switching power supply is DC instead of AC.

In the switch mode power supply network, LED power stations account for a large part, and the development prospects of LED power supply are very promising in the future. Before the arrival of the new technological revolution, the market share and territory of switching power supplies and LED switching power supplies on the network will continue to be maintained. Until this item is no longer necessary on the internet.
