    摘要： A circuit for converting AC voltage into DC voltage for one or two devices (Rm, Ra), includes a first part of the current being fed to the input side via a large induction coil (L50) and a first rectifier (Gm), and a second part of the current being fed via a second rectifier (Ga) upstream of the large induction coil. On the output side, behind the second rectifier (Ga), a switched-mode power supply is arranged, preferably in the form of an up-converter or a flyback converter (10). The division of the applied current for smoothing the output voltage provides that the induction coil (L50) can be accordingly dimensioned smaller and, despite this, the circuit can also satisfy relevant standard specifications.

    摘要： Power reception circuits employable in portable data devices (e.g., smart cards) to derive power and/or data from an input AC power signal (e.g., an ASK modulated carrier signal). In one embodiment, the power reception circuit comprises a power rectifier (120), a shunt rectifier (142) and a shunting element (132). The power rectifier (120) is adapted to rectify the input power signal, yielding a rectified output waveform. The shunt rectifier (142) is connected in parallel with the power rectifier (120). The shunting element (132) is connected to the shunt rectifier (142) and is operable to regulate an output voltage or current waveform produced at the output of the power rectifier (120). In another embodiment, the power reception circuit includes an analog circuit (610) for recovering data from a modulated carrier signal. A decoupling device (630) isolates the analog circuit (610) from impedance variations of a load. A shunt device (640) diverts undesired current from the load.
