CXLB7415 The wireless charging system consists of transmitter and receiver When the transmitter detects that there is a receiver close to it PWM is used to control the on and off of Q1

CXLB7415 The wireless charging system consists of transmitter and receiver. When the transmitter detects that there is a receiver close to it, PWM is used to control the on and off of Q1. The PWM frequency meets the formula: F = 1 / (2 Π√ LC). At this time, TX and CP are in the state of LC resonance. The flux produced by the electric field change of the transmitting coil (TX) will be coupled to the electric field produced by the receiving coil (Rx) so that the energy will be transferred from the transmitter to the receiver

产品概述                                             返回TOP

无线充电系统包括发射器和接收器两部分,当发射器检测到有接收器靠近时,通过PWM 控制Q1的导通和关断,PWM频率满足公式:F=1/(2∏√LC),这时发射线圈(TX)和谐振 电容(Cp)处在LC谐振的状态下。发射线圈(TX)电场变化产生的磁通量会耦合到接 收线圈(RX)使接收线圈产生交流变化的电场,这样能量就由发射器传递到了接收器dFB嘉泰姆
