Abstract:This article presents a novel commutation error closed-loop compensation method for the position sensorless brushless dc motor. A key challenge is addressed that the conventional closed-loop compensation method fails in the case of no available analog-to-digital converter (ADC). The proposed method consists of a commutation error sign detection circuit and a compensation algorithm. First, the voltage of the virtual neutral point with respect to dc-link midpoint is transformed to obtain a logic level. The logic level can indicate whether the commutation is advanced or delayed. Then, the logic l
