2, ZTE Tianji 10spro supports wireless charging. According to ZTE's official website: ZTE Tianji 10spro It supports Qi standard wireless charging Only need to use a wireless charger that supports Qi standard, wireless charging can be achieved. At the same time, the ZTE 10spro also supports 18W fast wired charging, and the fast charging function can make the battery fully charged faster and ensure a long time of battery life.
3, when investigating whether the 8002s phone supports wireless charging, we found that it can be charged via USB. However, the phone does not support Qi wireless charging technology, which means that users need to use a traditional data cable to charge, which cannot be achieved through a wireless charger. Although 8002The s phone does not support wireless charging, but it has other very useful features, such as fast charging.
4, the current wireless charging technology can only reach the longest transmission distance of 7 meters.
5, such as Qi for mobile phone charging, and ZTE's electric vehicle wireless charging mode uses inductive mode. High-power wireless charging typically uses resonance transmission of energy from the power supply device to the electronic device, which uses the received energy to charge the battery while providing its own operation. Since the charger and the appliance transmit energy through the magnetic field, there is no wire between the two, so the charger and the appliance can achieve no violenceExposure to electrical contact.
1, for high-power wireless charging roads such as new energy buses and new energy load trucks, whether they use constant current or constant voltage charging methods, due to high charging voltage and large charging flow, a constant power type NTC thermistor can be set at the input voltage entrance of the transmitter to prevent or weaken the harmful impact of inrush current on four MOS tubes. To increase the life of MOS tube, reduce the charging timeFailure rate.
2, the core of the principle of high-power wireless charger is energy transmission through the principle of electromagnetic induction. Specifically, the wireless charging system consists of two parts, namely the charger and the receiver. The charger converts electrical energy into a high-frequency electromagnetic field, while the receiver converts the electromagnetic field into electrical energy through an induction coil to achieve the process of charging. In the principle of high-power wireless charger, there are several key elements to consider. 3, wireless charging technology from the radio energy transmission technology, can be divided into small power wireless charging and high-power wireless charging two ways, its principle is through the near fieldInductive, the wireless charging device conducts the energy to the charging terminal device, and the terminal device converts the received energy into electrical energy stored in the battery of the device. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones.
Wireless charging PCB, different functions, the required components are different. The required components are: resistance,Capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
Taking Apple 11 as an example, the system version is iOS11, iphone11 supports wireless charging function, but if users want to use the wireless charging function of iphone11, they need to buy a wireless charger separately. The iphone11 is a mobile phone released by Apple Inc., which was released on September 11, 2019. The iphone11 features anodized aluminum and glass, an A13Bionic chip, and an ultra-wide-angle camera that supports 2x optical zoom.

When VdVg-Vth, NMOS works in the linear region, that is, the unsaturated conduction region, and is not a real conduction. Contrary to your understanding. The opening of high-voltage NMOS is about 2V, so the GS voltage of 30V is enough, or even high. Because the general DS can withstand a voltage of about 100V NMOS, its gate voltage is also20 or 30V, depending on your MOS manual.
