摘要：
A capsule device with an inductive powering apparatus is disclosed. The capsule device comprises a secondary coil to generate an induced secondary voltage when a first alternating magnetic field is coupled to the secondary coil externally. Embodiments of the present invention utilize a power conversion device to convert the induced secondary voltage into a DC output voltage for the capsule device. In particular, the power conversion device comprises a voltage booster to generate the DC voltage from a lower induced secondary voltage. Accordingly, the system can be operated using a lower secondary voltage, which will reduce the influence of magnetic flux on the circuit boards inside the capsule.
