This paper provides a formulation for the initiation or onset mechanism of commutation failures in line-commutated thyristor power converters, assuming infinite (zero impedance) AC systems. A theoretical development and a parametric analysis is given. Theory validation by simulation and comparison to actual field experience data is also given
