Abstract
A method for calculating a maximum output current of multiple thyristor converters connected in parallel, step: setting an operating time t; step: assuming a trigger angle; step: calculating a maximum output current of a single converter according to an output current model for the single converter; step: equally dividing a total output DC current into a plurality of parts according to a working duration of six converter bridge arms, thereby obtaining a pulse operating current of a single bridge arm; step: checking whether a present junction temperature of a thyristor is below a limiting temperature based on a thermal resistance model for the thyristor, if no, correcting the trigger angle, and repeating stepto stepuntil the condition is met; step: giving a present trigger angle; and step: giving a maximum output current of multiple converters connected in parallel.
