What are the advantages of switching power supply?
1. Low power consumption and high efficiency. In the switching power supply circuit, under the excitation of the excitation signal of the transistor V, it alternately works in the on-off and off-on switching states. The conversion speed is very fast, and the frequency is generally about 50kHz. In some countries with advanced technology, it can achieve several hundred or nearly 1000kHz. This makes the power consumption of the switching transistor V very small, and the efficiency of the power supply can be greatly improved, and its efficiency can reach 80%.
2. Small size and light weight. From the principle block diagram of the switching power supply, it can be clearly seen that there is no lightweight power frequency transformer. After the power dissipation on the regulator tube V is greatly reduced, a larger heat sink is omitted. Due to these two reasons, the switching power supply is small in size and light in weight.
3. Wide voltage stabilization range, the output voltage from the switching power supply is adjusted by the duty cycle of the excitation signal, and the change of the input signal voltage can be compensated by frequency modulation or width modulation. In this way, when the power frequency grid voltage changes greatly, a relatively stable output voltage can still be ensured. Therefore, the voltage regulation range of the switching power supply is very wide and the voltage regulation effect is very good. In addition, there are two methods for changing the duty cycle: pulse width modulation and frequency modulation. Switching power supply not only has the advantages of wide voltage regulation range, but also has many methods to realize voltage regulation. Designers can flexibly choose various types of switching power supplies according to the requirements of actual applications.
The advantages of switching power supply are introduced here, I hope everyone can use switching power supply safely!
