摘要: A simple and robust source-voltage-sensorless scheme for a PWM rectifier considering voltage unbalance conditions is proposed. When occurs in three-phase system, the component deteriorates performance of source estimator by generating AC disturbances. Since information used to control real/reactive power flow, inaccurate causes fluctuation DC-link, increase reactive power, furthermore, instability rectifier. In this work, proposed sensorless estimates normal components separately using modified reduced-dimensional estimator. The use measurement's derivative quantity sensitizing measurement noises avoided introducing an auxiliary variable. Thus, yields better robustness noises, it works well even transient state. feasibility confirmed through computer simulations experiments.
