Abstract
A power control unit is provided to monitor the output power of a charge pump converter having an input impedance and an input impedance controlling terminal to be plugged to the power control unit and modify the input impedance. The power control unit includes a control circuit sense the output power of the charge pump converter and a control unit to receive the sensed power value, establish a control value, and send the control value to the impedance controlling terminal so as to modify the input impedance.
