PROBLEM TO BE SOLVED: To obtain a rectifier having a simple configuration.SOLUTION: A control unit 9 controls the duty ratio of a switch 4 depending on the input power and the load resistor. When the duty ratio of a switch 4 is controlled so that the time average value of a load impedance viewed from a rectification section 1 has a value capable of obtaining a higher high frequency-DC conversion efficiency, in the rectification section 1, a higher high frequency-DC conversion efficiency can be obtained for a wide range of input power. Consequently, a rectifier of simple configuration can be obtained by not using a complicated connection switching circuit for switching series parallel connection state of the rectification section 1, but using a switch 4 of simple configuration for switching the output of the rectification section 1 on/off. |
