Rectifier technology, one of the key technologies of wireless charging chip, is analyzed

To be specific,Wireless charging chipThe transmitting end mainly consists of a power module, a transmitting coil, etc., which is used to generate a high-frequency electromagnetic field. The receiving end mainly includes a receiving coil, a rectifier module, a control module and other parts, which are used to receive the electromagnetic field and convert it into electrical energy. When the transmitter and receiver frequencies are the same, the magnetic field coupling intensity is the highest, and the energy transmission efficiency is the highest.

The rectifier technology plays the role of converting alternating current into direct current in wireless charging. The wireless charging system transmits electrical energy from the transmitting end to the receiving end through the principle of electromagnetic induction or magnetic resonance. The electrical energy received by the receiving end is alternating current, which needs to be converted into direct current through rectification technology to provide a stable power supply for the device. Rectifier technology is an important part of wireless charging system, and its conversion efficiency directly affects the efficiency of the whole wireless charging system.

Rectification technology can be implemented in different ways, such as mechanical rectifiers, transistor rectifiers, etc. In wireless charging system, transistor rectifier is usually used to realize the rectification function. Transistor rectifier has the advantages of small size, high efficiency and high reliability, which can meet the needs of wireless charging system.

In wireless charging system, rectification technology also needs to solve some special problems. For example, due to the long transmission distance of the wireless charging system, the transmission efficiency will be affected. Therefore, it is necessary to adopt efficient rectification technology to minimize energy loss. In addition, due to the large voltage and current in the wireless charging system, large heat may be generated, so it is necessary to use a good heat resistance rectifier to ensure the stability and reliability of the system.

In short, rectification technology plays a role in converting alternating current to direct current in wireless charging, and is one of the key technologies to achieve efficient, stable and reliable wireless charging. With the continuous development of wireless charging technology, rectification technology will also continue to improve and improve, providing a broader prospect for the application of wireless charging.
