Abstract

A method for controlling line-commutated converters in discontinuous conduction mode is presented. The proposed strategy is based on the modification of the tiring angle alpha in order to produce the same effects on the average output current regardless the conduction mode. The compensation is based in an on-line estimation of the rectifier average output current in order to achieve the compensation angle. Simulations on a high-precision current control system are presented.
