摘要：
Various exemplary embodiments relate to a current driver for controlling a current source controlled by an alternating current (AC) signal, including: a current sensor configured to measure an output current from the current source; a threshold detector configured to detect when the measured current is below a threshold value; and a controller configured to control the current source using a duty cycle of the AC signal when the measured current is below the threshold.
