Abstract
A power supply circuit and a transponder having a circuit for rectifying an A.C. voltage and two power storage elements, the rectifying circuit providing a rectified voltage to at least one of the storage elements and an output voltage being provided by at least one of the storage elements, and at least one switching element for switching the circuit operation between a state of provision of a relatively high voltage and a state of provision of a relatively low voltage, the second state configuring the rectifying circuit in halfwave operation.
