| 摘要 |
The invention relates to a device for converting radiofrequency energy into DC current, receiving as input at least one radiofrequency signal and generating as output a DC current able to power at least one load, comprising at least two conversion stages each comprising: a radiofrequency filtering module (411), connected to a first input node (E1) of the conversion stage, configured to filter the radiofrequency signal; a voltage shifting module (412), connected between a second input node (E2) of the conversion stage, the radiofrequency filtering module (411) and an intermediate node (A) of the conversion stage, configured to displace a voltage present at the level of the first input node (E1) onto the intermediate node (A); a voltage rectification module (413), connected between the intermediate node (A), the second input node (E2) and an output node (B) of the conversion stage, configured to rectify the voltage of the intermediate node (A) and to deliver a rectified voltage on the output node (B). |
