As a new member of semiconductor materials, gallium nitride has three characteristics: high switching frequency, large band-gap width, and lower on-resistance. Switching frequency refers to the number of times per second that electronic components such as thyristors and thyristors inside the charging head can be fully switched on and disconnected. The high switching frequency can reduce the volume of the transformer and capacitor, which helps to reduce the volume and weight of the charging head.
AC/DC power adapter, also known as a power supply or AC adapter. It is an electronic device that converts alternating hing AC power 90v-240v from a wall outlet into low DC power 5v-56v that can be used by electronic devices,such as laptop,air purifier,robot,la mp ... It typically consists of a transformer, rectifier, and voltage regulator, which work together to provide a stable and consistent source of DC power to the device. When we choose power adapter need know what is the dc output voltage and ampere of our device.
