Because for the current industry market, inferior power adapters account for about 30% of the market. It is a big threat to our factories that make high-quality products, because the unit price of power adapters produced with second-hand originals will be 30% or more cheaper than the unit price of our brand-new materials. As a result of the chaos in the current market, some manufacturers are struggling with prices, and quality has not received much attention. It is a big hidden danger for customers and terminal consumers. usb power adapter
First, it can enhance the design of the input/output filter circuit, improve the performance of the active power factor compensation (APFC) circuit, reduce the voltage and current rate of change of the switch tube, rectifier, and freewheeling diode, and use various soft switching circuit topologies. Structure and control methods, etc.; on the other hand, strengthen the shielding effect of the case, improve the leakage of the gap of the case, and conduct a good grounding treatment.
In order for the notebook computer to work stably, a stable DC voltage must be provided. This device that provides a stable DC voltage is a DC stabilized power adapter. This DC stabilized power adapter, in addition to providing a stable DC power adapter for the electronic circuit of the notebook computer, is also required to have high reliability, safety and environmental resistance. usb power adapter
There are generally two types of power adapters: one is a switching power supply, and the other is a transformer-type power supply. Switching power supply circuit is more complicated, with more components, it is a new type of power supply. The latter is a very common power supply with relatively simple components, mainly including step-down transformers, rectifier diodes, filter capacitors, etc., and the higher-end ones are also composed of voltage stabilization protection circuits.
