Technology overview
High-quality factor magnetic induction-based wireless power transfer
Intelligent
Quasi-resonant commutation minimize the losses and increase the resonant frequency up to tens of MHz; resonant curve rupturing, switched capacitors and a variable capacitor use for automatically tuning to resonance and agree the impedances.
Efficient
Accounting of parasitic parameters transforms circuit limitations to its advantages, special geometry maximizes of flux density whereas keeping of the optimal B-H trajectory minimizing of ferrite core losses and selective properties.
Low power losses
Quasi-resonant switches control strategy allows minimizing the power losses on semiconductors.
Optimal hysteresis
Selection of optimal BH-curve trajectory depend on load impedance allows minimizing of ferrite core losses.
Bidirectional converter
Bidirectional converter allows each end-point device became a transmitter, as a result, creation of wireless mobile smart-grid with power balancing and energy harvesting.
Effective
Highly-selective resonance tuning eliminates losses caused by influence onto non-native contours.
