Abstract
Abstract:
This paper focuses on designing and modeling multiple-output wireless chargers for electric
vehicles (EVs). This paper uses a closed loop buck converter to obtain variable output dc voltage
of a wireless electric vehicle charger (WEVC). For designing a closed-loop buck converter, a PI
controller is used. The tuning of a PI controller for a nonlinear system is a typical task; therefore, in
the paper, three optimization techniques such as Krill Herd Optimization (KHO), Harris Hawks Optimization
(HHO), and Sparrow Search Optimization (SSO) utilized to find the optimum value of a
PI gain parameters (Kp and Ki).
Background:
Wired charging system is famous but contains problems like unkempt wires and protection
concerns in a damp environment. Then a solution to this problem is a wireless charger because
it does not contain any exposed wires. Hence it is convenient for charging and intrepid transmission
of power in antagonistic environmental conditions. A wireless charger can be used in unmanned
electric vehicles.
Objective:
The objective of this study is to develop a wireless electric vehicle charger at the variable
output voltage. The performance analysis by different optimization techniques such as SSO, KHO,
and HHO for variable reference output voltage.
Methods:
Three optimization techniques are used, such as SSO, KHO, and HHO, for obtaining
smooth output dc voltage, reducing harmonics, and improving power transfer capability.
Results:
SSO gives better results for the variable output voltage of the wireless charger.
Conclusion:
Wireless charger is designed at a variable reference output voltage and SSO-optimized
PI-gain parameters of the charger and provides better performance than other optimization techniques,
such as HHO and KHO.
