Abstract
Methods and apparatuses for controlling an apparatus comprising a controller integrated in a first slave device. In an example, the controller can detect a sensed current of the first slave device. The controller can receive a voltage signal associated with a second slave device connected to the first slave device. The controller can generate a correction current based on the sensed current of the first slave device and the voltage signal. The controller can modulate a pulse width modulation (PWM) signal received by the first slave device using the correction current. The controller can control a power converter using the modulated PWM signal.
