Abstract: This paper proposed an analytical model and optimal design for wireless power transmitting system used for gastrointestinal robots. Based on the phase-shift PWM controller UCC3895, a wireless power transmitting circuit which is suitable for large-sized coils and large driving current conditions was designed. The system has the characteristics of stable operation, adjustable frequency and power. We optimized the number of turns of a single-layer transmitting coil with a diameter of 69cm according to the analytical model and the feasible region analysis of the coil. The results show that at the operating frequency of 218kHz, the power transmitting system can provide up to 650mW for endoscopic robots with a transmission efficiency of 3.60%.

Key words: gastrointestinal robot, wireless power transfer, transmitting coil, full bridge inverter
