Abstract: A microwave-rectifying circuit for rectifying AC power is equipped with: an input line into which AC power is inputted; multiple branch lines which branch off from the branching point on the output side of the input line into n lines; rectifiers which rectify the AC power flowing through the branch lines and are positioned in each of the multiple branch lines; and phase shift units which are provided upstream from the rectifier in at least n−1 branch lines among the multiple branch lines, and shift the phase of the AC power in a manner such that relative to the AC power which flows through one branch line and arrives at the corresponding rectifier, the AC power which flows through each of the other n−1 branch lines and arrives at the corresponding rectifier exhibits a phase difference of k×180/n°.
