What is switching power supply?

Linear power supply is a DC voltage with small ripple voltage which is obtained through the below process: first reduced the amplitude of AC power through transformer then become the pulsed DC after the rectify by a rectifier circuit.Finally got after filtering wave. To achieve high-precision DC voltage, it must be stabilized by a voltage regulator circuit.
Linear power equipment works in a linear state, that is to say, the power equipment is always in operation once it is used, so its operating efficiency is low, generally 50% to 60%, and it is large in size, low in efficiency, and high in heat-generating. But the linear power supply has the advantages that the switching power supply does not have: small ripple and good adjustment rate. Suitable for use with imitating circuits, various amplifiers, etc.
A. Advantages of linear power supply: stable performance, no interference such as high frequency ripple.
B. Disadvantages of linear power supply: high heat generation and low energy utilization. There is no super-powered power supply to choose.
Switch Mode Power Supply
Switch Mode Power Supply (SMPS), also known as switching converter, is a high-frequency electric energy conversion device and a type of power supply. The principle of switching power supply mainly includes input grid filter, input rectification filter, converter, output rectification filter, control circuit, and protection circuit. Its function is to convert a level of voltage into the voltage or current required by the user through different forms of architecture. The input of the switching power supply is mostly AC power or DC power, and the output is mostly DC power that equipment requires.
A. Advantages of switching power supply: low power consumption, high efficiency, small size, light weight, wide voltage regulation range.
B. Disadvantages of switching power supply: large ripple and switching noise.

The linear power supply technology is very mature, the production cost is low, it can achieve high stability and small ripple, its own interference and noise are relatively small, but the volume of the transformer is relatively large, and the efficiency is partial low.The overall volume is relatively large, it is relatively heavy, and the input voltage range requires high. However,the switching power supply is in a high-frequency state of work. The volume of the transformer is relatively small and relatively light, but the output ripple is larger than that of a linear power supply. But due to its simple structure, low cost and high efficiency (the efficiency of switching power supplies on the market can also be Up to 90%). With the increasingly developing of electronic technology, the design of switching power supply is becoming more and more scientific. The shortcomings of switching power supply will gradually be weakened or even eliminated, So switching power supply will be the mainstream trend of future applications and gradually replaces the linear power supply.
Our company has 10 years of experience in R&D(research and development) and production of switching power supply. We mainly produces LED power supply in the category of switching power supply. We have a professional R&D team and flexible production deployment. The productions includes constant voltage, constant current, isolated and non-isolated categories. For switching power supply, each type of productions will be certified by a professional certification authority.What's more,we provide corresponding customized services according to customer needs. The advantages of our products can be understood from the following products I introduce:
Fig.1 Constant voltage LED power supply HZD100AYI

Fig.2 HZD100AYI

As shown in Figure 2, this is the relevant performance that our products basically have. Each of our products has the characteristics of high efficiency, stable performance, small size, high cost performance, energy saving and environmental protection. In addition, our products can also achieve constant current, waterproof, dimming (0-10V, PWM, Taric, R), adjust the output parameters corresponding to the needs, etc. to meet the needs of different customers.
