Abstract: In view of problem that working state of traditional inductive coupled power transmission (ICPT) system deviates from optimal operating point as the load changes, H-bridge converter is introduced to replace traditional compensation capacitor in ICPT system, and dynamic adjustment of compensation capacity and tracking of optimal operating points are achieved by changing its trigger angle. Compensation capacity-load matching mathematical model under optimal operating point of ICPT system is established according to circuit mutual inductance theory. The maximum power point is used as the optimization target, and ICPT topology and impedance matching control method based on dynamic compensation of H-bridge converter are given. Matlab simulation results show that the range of trigger angle α of H-bridge converter is α<40°; experimental results show that the ICPT topology based on dynamic compensation of H-bridge converter has good dynamic compensation characteristics, which can automatically track the optimal operating point of ICPT system as the load changes.
