Investigation in Thyristor-Controlled Reactor (TCR)

The paper studies the single phase Thyristor-Controlled Reactor (TCR) which is one the important applications of thyristors (Silicon-Controlled Rectifier, SCR). The TCR is mainly used as a reactive power compensator. The paper also presents experimental results and theoretical calculations of the TCR circuit. At various firing angle of the thyristors, the experimental results include the thyristor current, reactor current, RMS values of the power supply, current and voltage harmonics are plotted and tabulated. The relative results of the TCR system are also compared and discussed.
