Single switch capable of blocking 10 kV and higher voltages are presently being developed and demand improved gate drivers for their functioning. Induction based gate drivers have been the foremost solutions in this regard. Design challenges that have been outlined for these drivers are low coupling capacitance, strong magnetic coupling and smaller dimensions with isolation not considered in depth...
Input current of wireless power transfer system is limited by current rating of power converter on the primary side. Power rating of wireless power transfer system increases linearly with the quality factor for series-parallel topology of the system at a given primary current. Magnetic emissions to the surroundings also increase with increase in the quality factor. In this paper, first analytical...
Magnetic fields emitted by wireless power transfer to vehicles can potentially affect living organisms. As a result, minimizing the magnetic emissions without compromising with the power transferred is one of the most significant challenges in the success of this technology. Active and passive shielding methods are used for screening of the magnetic fields of this system. In this paper, a new active...
Inductive power transfer is non-contact transfer of energy by means of magnetic fields. A higher secondary side quality factor at fixed input current ensures a linear increase in power transfer across the air gap. But also at the same time magnetic emissions to the surroundings increase. First of all in this paper an analytic expression for comparing the magnetic emissions at different quality factors...
