Abstract

The rectifying device converts high-frequency power input from an input terminal into direct current power and outputs the direct current power from an output terminal. The rectifying device includes a rectifier that converts the high-frequency power into the direct current power, and an impedance changer having one end connected to a connection point of the rectifier and the output terminal and the other end to which reference voltage is applied such that impedance varies while having a negative correlation with respect to an absolute value of voltage of the direct current power. When the absolute value of the voltage of the direct current power is greater than a predetermined value that is lower than reverse withstand voltage of the rectifying element included in the rectifier, the impedance of the impedance changer as viewed from the rectifier is a value regarded as corresponding to a short circuit.
