Abstract In this paper, a detailed theoretical analysis of thyristor latch-up when capacitor banks of low-voltage TSC switched repeatedly is presented and the probability of the latch-up is calculated. The effect of capacitor losses, discharge resistance and residual voltage of the capacitors on response time is analyzed in practical application. A control strategy is proposed to avoid the thyristor latch-up, and the response speed and reliability of the device are increased. Simulation and experimental results verify the theoretical analysis and show that the control strategy is feasible and efficient.

Key words： Thyristor switched capacitor(TSC) zero transition repeated switching latch-up probability
