Abstract
A level shifter for a power converter includes: a differential detector; a first transistor having a drain electrically connected to a first node of the differential detector, a gate electrically connected to ground or a fixed DC voltage, and a source; a second transistor having a drain electrically connected to a second node of the differential detector, a gate electrically connected to ground or a fixed DC voltage, and a source; a first circuit configured to dynamically control a voltage applied to the source of the first transistor based on a digital signal input to the level shifter; and a second circuit configured to dynamically control a voltage applied to the source of the second transistor based on the digital signal. The differential detector is configured to translate the digital signal to a different voltage level based on a differential current between the first transistor and the second transistor.
