What happens if the thyristors in a TCR are fired at an angle below 90 degree ?

26 June 2023 0 2K Report

TCR consists of a linear reactor in series with anti-parallel thyristors. Firing angle in a TCR typically varies from 90 degree to 180 degree. We know that current lags the voltage by 90 degrees in a reactor. Is this the reason behind specified firing angle range or there is something else?

What happens if the TCR is fired at an angle below 90 degree?
