摘要/Abstract:
A Wireless Power Transfer (WPT) system with a simplified Receiver (RX) is proposed for Implantable Medical Devices (IMDs) in this paper. This system utilizes LCC-S compensation of the coupling coils for rough voltage regulation and global control for fine voltage regulation and high efficiency. To further reduce the cost, data transmission is realized based on the coupling coils. This method minimizes the components in the receiver, reducing the receiver volume and making it very suitable to wirelessly power the IMDs. A prototype is built up and the board-level experimental results validate the effectiveness of the proposed method. With the modulation signal based on Load Shift Keying (LSK), data communication through the energy link and adjustment of transmitting power in primary side, the system can adjust output voltage automatically. From the measurement results, the system power efficiency can achieve 49% at 5.1 V output voltage.
