Analysis, modeling and eva‎luation of the effect of the nature of the load and its changes on the performance of the wireless power transmission system for the medical system implanted in the body

Wireless power transmission systems have replaced traditional methods for power transmission due to their many advantages. One of the main applications of this system is in the field of medicine. Where supplying the power of the implantable medical parts inside the patient's body, including the brain, heart, etc., is a very vital matter, and if it is not done correctly, it will cause the implanted part to malfunction, which seriously affects the patient's health, It poses a risk. In most of the articles that have investigated the issue of wireless power transmission in the field of medicine, for simplicity of analysis, the load that is going to be implanted inside the body has been considered as a simple resistance. While in practice we know that the part that is implanted in the patient's body for various purposes, such as a pacemaker, nerve stimulator, etc., is an electronic circuit that may include digital and analog parts. Where the power source is a battery or a large signal source, this issue may not be very important, but in low-power applications where we have little power consumption and in the wireless power transmission system where all connections and links depend on burden, this issue becomes very important. Digital parts do not work constantly and sometimes they may not be active or some parts may be active at different speeds in the circuit at different times. Therefore, this load behavior affects the amplifier in different ways and is not like a normal resistor. The aim is to investigate the effect of this load behavior and load changes on the wireless power transmission system. Therefore, we have to model the power consumption of the load and apply it to the wireless power transmission system in order to examine the performance of the system.
