Characteristic of Constant Current of Non-Contact Energy Transfer with Parallel Resonant and Bridge Rectifier

摘要

Change of load voltage and current with the load change becomes very large in the non-contact energy transfer using a magnetic coupling. This is caused by a leakage inductance of the detachable transformer and load matching capacitor. Further this differs by the output rectifier way. A combination of parallel resonant load matching and bridge rectifier has a constant current characteristic. Author researches the mechanism and investigated the characteristic of constant current ability by circuit analysis.
