Hi people, I'm new here just registered.
So I am writing about a problem I am having regarding some simulations(Simulink) a have been doing for my master thesis.
My goal is to design an inductive wireless charger that uses a resonant tank to maximize the efficiency of the process. I am going to add some pictures of the circuit so I can illustrate better the issue I am having.
You can see in the first picture that this is still a simple simulation where I have a Full bridge inverter connected to a DC source to supply power to another circuit that has a seriesseries topology for maximizing the power transfer. Then on the exit, there is another fullbridge rectifier to convert the signal to DC to charge a supposed batterie.
This simulation is based in many other that I have researched but I have used the data of another simulation published in an article: https://bit.ly/2WFg7bh (Page 3744)
And so now mentioning the problem I am having, while in the article the waveforms of the primary voltage and current are in phase and also the voltage and current from the secondary wing of the resonant tank my waveforms (voltage and current on both sides) are shifted 90 º something that I don't understand why since all the parameter of the circuit are the same of the article. The capacitors are calculated using the formula 1/(wress^2*L) so that the tank is working in resonant frequency. I will add another picture of the waveforms.
Sorry for the long text but I will end here the explanation of my problem and give more details if someone knows what I should do. Due to the current state of the world, it has been hard to get help from my university professors because of the quarantine everyone is obliged to do in my country .
I hope I was clear enough with my English.
Thanks in advance and stay safe.
