Abstract: Example implementations include a method of reducing current overshoot in a power regulator device, by detecting a change in an input current of an inductive charger device in response to a change in load on the inductive charger device, modifying an operating state of the inductive charger device in accordance with a first input current limit parameter based on a total input current limit parameter and a current division parameter, in response to the detecting the change in the input current, operating the inductive charger device in accordance with the first input current limit during a current limit period subsequent to the detecting the change in the input current, modifying the operating state of the inductive charger device in accordance with a second input current limit parameter based on the total input current limit parameter and the current division parameter, subsequent to the current limit period, and operating the inductive charger device in accordance with the second input current limit subsequent to the current limit period.
