Abstract
In wireless power transfer (WPT) systems, output power (Pout) can be controlled through input parameters such as, input voltage (Vin), duty cycle (d), and switching frequency (fsw). The impact of these control parameters on the overall system efficiency has not been explored in previous studies. This paper focuses on the efficiency (η) and Pout sensitivity to these control parameter variations in an LCC-Series tuned WPT system. There are multiple combinations of Vin, d, and fsw that can achieve a specified target Pout. However, it is important to determine the optimal combination of these control variables that will yield the maximum η for a target Pout. A MATLAB/Simulink model is built to calculate and measure η and Pout. In order to achieve this result, several simulations are run where Vin,d, and fsw are swept across a wide range to cover all possible combinations. MATLAB's Sensitivity Analysis toolbox is used to evaluate how the parameters influence the model's output. Finally, an experimental prototype is implemented. The optimal values acquired using the sensitivity analysis is then plugged into the hardware prototype and compared with the simulation. The results obtained confirm the validity of the proposed method.
