In power electronics, particularly within power adapters, deadtime voltage errors occur during the transition between switching devices when both are off to prevent short circuits. This delay, or "deadtime," introduces voltage distortions that reduce efficiency, causing power losses and heat generation. This is particularly problematic in multilevel inverters utilizing wide-bandgap (WBG) semiconductors, which are critical for high-efficiency power adapters.

In the manufacturing process of power adapters, the surface treatment process is one of the important factors that determine the product appearance, durability, corrosion resistance, etc. Common surface treatment processes include electroplating, spraying, anodizing, brushing, etc. The following is a technical analysis of various surface treatment processes and their applications in power adapters.

With the popularity and development of electronic devices around the world, power adapters play a vital role as core components that provide stable power for various devices. Inside the power adapter, power semiconductors are one of the key technologies for achieving efficient power conversion and transmission.

The USB Power Delivery (PD) protocol is a fast charging standard launched by USB-IF, which supports efficient and safe charging through the USB-C interface. The PD protocol can flexibly adjust the voltage and current to meet the different power requirements of devices from smartphones to laptops. The latest PD 3.1 version supports up to 240W output. With its wide compatibility, PPS fast charging function and strong power support, it has become the mainstream solution of current fast charging technology and is suitable for various smart devices and high-power scenarios.
