Abstract
A conversion system includes a conversion device including a multilevel inverter configured to generate two alternating current (AC) output currents, a current sensor configured to sample a current through the multilevel inverter, or from the multilevel inverter, during a switching cycle, and a processor configure to estimate both of the two AC output currents based on the sampled current from the current sensor.
