RECTIFIER AND WIRELESS POWER TRANSMISSION SYSTEM |
摘要 |
<p>A rectifier comprises at least: a diode that rectifies input RF power; an input circuit that prevents leakage of DC power to an RF input port; a high-frequency control circuit that has a frequency characteristic that is in short-circuited condition with respect to some or all frequencies that are even multiples (2×n×f0 (where n is a positive integer)) of the frequency (f0) of the input RF power, and that is in open condition with respect to other frequencies; an output circuit having a frequency characteristic constituting a low pass filter that prevents passage of RF power and that delivers to the DC output port DC power that has passed through this low pass filter. The anode terminal of the diode is earthed and the output circuit and the high-frequency control circuit are connected in parallel to the cathode terminal of the diode. The input circuit and the high-frequency control circuit are connected between the RF input port and the cathode terminal of the diode.</p> |
