Abstract
A power conversion device includes: a plurality of legs, each leg including a high-side switch connected between a voltage supply node and a phase node and a low-side switch connected between the phase node and a reference node; a phase current sensor for each leg and configured to sense current flowing through the high-side switch or the low-side switch of the corresponding leg; a single current sensor connected between the reference node and the low-side switches, or between the voltage supply node and the high-side switches; and a controller. During a subperiod of a switching period, the controller is configured to sample the current sensed by at least one of the phase current sensors and a current sensed by the single current sensor such that the current in one or more of the legs is sampled during the same subperiod as the current flowing through the single current sensor.
