摘要:
定频PWM(pulse width modulation)控制模式下发射/接收线圈电流频谱能量集中,导致对外电磁干扰水平较高.将混沌载频调制技术应用在电动汽车无线充电系统的高频逆变器中.这种调制技术能够展宽发射/接收线圈的电流频谱,将相同的传输能量类似随机地分布在不同的频线上,从而改善空间电磁场的频率谱,降低了无线充电系统对外电磁干扰水平.计算机模拟和实验结果都证明了方法的有效性.
Abstract:
In the fixed-frequency PWM (pulse width modulation) control mode, the current spectrum energy of the transmitting/receiving coil is concentrated, resulting in a high level of external electromagnetic interference. The chaotic carrier frequency modulation technology is applied to the high-frequency inverter of the electric vehicle wireless charging system. This This modulation technique can broaden the current spectrum of the transmitting/receiving coil, distribute the same transmission energy on different frequency lines similarly randomly, thereby improving the frequency spectrum of the space electromagnetic field and reducing the external electromagnetic interference level of the wireless charging system. Computer simulation and The experimental results have proved the effectiveness of the method.
