Researchers are showing significant interest on wireless charging of electric vehicles (EVs) and this concept is becoming popular and growing very fast. Using wireless charging technique, it is possible to considerably decrease fossil fuel consumption and reduce pollution created by vehicles in one hand and reduce electric cord hazards in EV charging on the other hand. EV wireless charging systems can be divided into two groups: Stationary Wireless Charging (SWC) and Dynamic Wireless Charging (DWC). However, DWC has more advantages as compared to SWC, in terms of charging time and reducing battery size. Despite of the fact that DWC has more positive sides, there are issues with efficiency of the system since the vehicle charges once it is in motion. One of the possible ways to solve this problem is reduction of power pulsations while dynamically charging. This study discusses and analyzes the effect of distance between adjacent transmitter coils on DWC system output. Mathematical modeling for multi-channel DWC is carried out and simulation is performed with different distances between transmitter coils and the results are discussed in detail. A possible solution to reduce pulsation is provided and future work is discussed
