A novel analysis view on bifurcation-frequency-based S-S compensation for wireless charger is introduced. Tx current stress of conventional leakage-inductance-compensation (LIC), self-inductance-compensation (SIC) and bifurcation-frequency-based compensation (BFRC) are derived theoretically. Simulation models are built to prove BFRC is with the lowest Tx current stress, especially in the case of poor coupling. Lower Tx current stress with lower output power is another benefit of BFRC, which has also been proven.

摘要

A novel analysis view on bifurcation-frequency-based S-S compensation for wireless charger is introduced. Tx current stress of conventional leakage-inductance-compensation (LIC), self-inductance-compensation (SIC) and bifurcation-frequency-based compensation (BFRC) are derived theoretically. Simulation models are built to prove BFRC is with the lowest Tx current stress, especially in the case of poor coupling. Lower Tx current stress with lower output power is another benefit of BFRC, which has also been proven.
