Switching power adapters are indispensable in our daily lives, and many digital and electronic products require their use. Whether we are charging commonly used mobile phones, cameras, or small electronic devices, switching power adapters are necessary. So why are these switching power adapters so widely used in people's lives today? What are their advantages? Today, let's discuss some of the advantages of switching power adapters.
First, let's examine the differences between switching power adapters and linear power supplies:
- Because switching power adapters do not require the power frequency transformer used by linear power supplies, their size and weight are only about 20% to 30% of those of linear power supplies.
- The power transistor in a switching power adapter operates in a switching state, which means the power consumption of the transistor is low, and naturally, its conversion rate is high, generally around 60% to 70%, whereas linear power supplies only achieve about 30% to 40%.
Additionally, switching power adapters are favored for their small size and light weight. Even when we do not carry bags or other containers, their compact and portable design allows us to conveniently slip them into our pockets. Therefore, they are very easy to carry. Generally, a switching power adapter serves multiple purposes, so we only need to carry one when going out daily. The diversity of functions adds versatility to our daily lives, making them more convenient and adaptable.
Modern switching power supplies can be divided into AC switching power supplies and DC switching power supplies. They are generally composed of a main circuit, detection circuit, auxiliary circuit, and control circuit. The simpler component structure and more efficient usage are also direct reasons for their wider adoption.
These advantages have led to the widespread use of switching power adapters in mechanical automation equipment, medical devices, security equipment, LED lamps, military products, and many digital products. Moreover, the development and application of switching power supplies also play a crucial role in environmental protection, such as energy conservation and pollution reduction.
