Abstract
This paper presents a novel, sensorless, current-sharing, algorithm for multiphase power converters, based on gradient estimation via low-frequency perturbation of the duty-cycle input to each phase. The algorithm eliminates the need for current sensing, and is particularly useful when allied to a digital controller, because the only analogue-to-digital conversions necessary are measurements of the output and input voltages
