    Thank you Sam for presenting the factors involved in inductive charging with such clarity of mind. Very interesting that the real power transfer has only one optimal operating point, which depends on pretty much all the parameters involved including K, which depends on how far away the charge circuit is from the load circuit.
    Beautiful analysis.

      Thank you for sharing your thoughts and kind words. Indeed, this is a tricky circuit, leaves a lot of room for new innovations.

    Professor Sam Ben-Yaakov, your simulation has demystified the formula and simulation to determine bifurcation or frequency splitting in a WPT I have been looking for more of a scenario, than a formula that can prove this for long. I wonder what the operating point will look like with a real EV battery internal imepedance of 20mOhms to 40mOhms. Thank you for your lectures. I shall be citing your videos in my PhD Thesis.

      The ESR has little if any effect on EV WPT since the voltage drop on it is less than a Volt.

    Hello Sam, thank you for this great video, very clear as always! :) I've been working on this topic for a few years now, and we have a technical article which presents a way to drive the rectification stage impedance regardless of the operating point (battery voltage or power operation), in line with your work and available on MDPI platform "Enhancing Wireless Charging for Electric Vehicles: Active Load Impedance Matching and Its Impact on Efficiency, Cost and Size"
