Sažetak
This paper observes impact of the various chokes on resonant frequency for the two different topologies of current-mode class-D (CMCD) amplifier used in the transmitter side of wireless power transmission (WPT) system. Both topologies are evaluated through measurements and simulations and the chokes with different inductance values were selected and applied to determine their impact on transmitter performance. In resonant WPT system, in particular transmitter subsystem, we suggest CMCD amplifier with center tapped transmitter coil. The most relevant features that are achieved, using CMCD amplifier with center tapped transmitter coil, in comparison to common CMCD amplifier are decreased choke voltage and significantly lower impact on resonant frequency.
