Circuit parameter optimization of class E power amplifier for wireless power transmission applications
Pages 1162 - 1166
Abstract
The parameters of class E power amplifier are optimized for achieving zero voltage switching (ZVS) condition in the magnetically coupled resonance wireless power transmission (MCR-WPT) system. Considering that the working frequency of MCR-WPT is very high, the influence of the parasitic capacitance of the MOSFET can't be neglected. The optimized value of capacitor and inductor are obtained by circuit theory. The performance of the ZVS with the optimized value is verified with circuit simulation by evaluating the output power and efficiency of MCR-WPT system. Under the condition that the coupling coefficient (k) is 0.3, the transmission efficiency of the WPT system was as high as 87%, which was increased by more than 20% on the original basis.
