摘要
针对磁耦合谐振式无线电能传输(MCRWPT)系统接收端,研究实现所需功率调节的效率最大点追踪,提出了基于脉冲密度调制/脉冲宽度调制(PDM/PWM)混合控制的功率控制策略,该方法通过控制占空比和调节可控延迟来实现功率的连续调节或按需调节。经过实验测试,验证了此控制策略能够实现所需功率调节的效率最大化传输,并且可以应用于负载变化的场合。
Aiming at the receiver of the magnetically coupled resonant wireless power transmission (MCRWPT) system, the maximum efficiency point tracking is studied to realize the required power regulation.A power control strategy based on pulse density modulation/pulse width modulation (PDM/PWM) hybrid control is proposed.The method realizes continuous power regulation or on-demand regulation by controlling duty cycle and adjusting controllable delay. Experiments show that the control strategy proposed can achieve the required power regulation and the maximum efficiency by active parameter detuning which also can be applied to the situation with variable load.
