  • Method and system for transmitting the power of a radio frequency type signal received by a radio frequency receiver
    Patent number: 11190056
    Abstract: A method and device for transmitting (20) to an electrical element (4) the power of a radio frequency type signal received by a radio frequency receiver (1), e.g., a radio frequency identification (RFID) chip, the receiver (1) having a receiving antenna (2) and a voltage rectifier (3) of the signal received by the antenna (2), the transmission device (20) including a voltage converter (30) connected to the rectifier (3) of the chip and to the electrical element (4). The device includes a control system (40) configured to momentarily derive the signal from the rectifier (3) in order to define an optimal input voltage of the converter (30) for which the input impedance of the converter corresponds to the output impedance of the rectifier (2), and to redirect the DC signal to the voltage converter (30) by providing the converter with an input voltage setpoint corresponding to the optimal voltage.
