The core components of USB phone charger are power electronic semiconductor devices, and their main function is to convert alternating current into low-voltage direct current. This process seems simple, but in fact it involves many profound theories of power electronics. First of all, the voltage and current of alternating current change with time, while direct current is constant. Therefore, the charger pin types needs to convert the alternating current into pulsed direct current through a rectifier, and then convert the pulsed direct current into smooth direct current through a filter. In addition, the 48W multi port charger also needs a voltage converter to reduce the voltage to a level suitable for charging mobile phones.
USB charger plug can not only provide powerful power to charge mobile phones quickly, but also has the advantages of small size and easy portability. This is because issues such as power supply efficiency, thermal effects, and electromagnetic compatibility need to be taken into consideration during the design and manufacturing process of the charger. In order to improve the efficiency of the power supply, USB adapter usually use switching power supply technology to store energy in the inductor or capacitor through the switching action of the switch tube, thereby reducing energy loss. In order to solve the problem of thermal effects, USB battery charger usually adopt efficient heat dissipation designs, such as metal casings, heat sinks, and fans. In order to solve the problem of electromagnetic compatibility, apple fast charger iphone 14 usually use shielding and filtering technology to reduce electromagnetic radiation and electromagnetic interference.
In order to ensure the safety of device charging, type c charger also has overload and overcurrent protection devices. When the output current exceeds the set value, the protection device will automatically cut off the power supply to prevent the battery from overheating and damage.
