In series-series compensated wireless power transfer, input voltage control and operating frequency control methods are used to improve the problem of output voltage change according to load variation. However, if two methods are used to maintain the output voltage, the efficiency of the circuit and the power loss of each element change. Therefore, in this paper, the characteristics, advantages and disadvantages of these methods are compared and analyzed through simulation. For this, the coil and circuit parameters are calculated using COMSOL simulator and design equations to model the circuit, and the performance of the two methods is compared and analyzed with PSIM simulator. In the simulation, when the load changes from 4.5Ω to 9Ω at an output power of 9W to 18W, the output voltage is maintained at 9V by using the input voltage or frequency control methods. As a result of the simulation, the input voltage control method produces an output voltage of 9V in the entire load range by increasing the input voltage even if the voltage gain is not sufficient, and has the maximum efficiency of 86.55% at a load of 4.5Ω. On the other hand, the frequency control method can not produce an output voltage of 9V because the voltage gain is small at a low load, and the circuit efficiency decreases due to an increase in the reactive current at a high load.
