Abstract
A 13.56 MHz wireless power transfer system with
a 1X/2X reconfigurable resonant regulating (R )r e c t i fi e ra n d
wireless power control for biomedical implants is presented.
Output voltage regulation is achieved through two mecha-
nisms: 1) a local PWM loop at the secondary side controls the duty
cycle of mode-switching of the rectifier between the 1X and 2X
modes; and 2) a global control loop obtains the mode-switching in-
formation from the secondary sid e and send it back to the primary
side
