Two Novel Main Circuits and their Triggering Modules of the Thyristor Switched-capacitor (TSC)

Based on the principle of TSC, two novel designs for the main circuits and their triggering modules of TSC, which could work reliable with fewer electronic components and cost less, are discussed in the paper. Called “2+1”circuit and “2+2”circuit. When the switch is on, no impact current is resulted and smooth transition is achieved. The paper also introduces the mechanism of “2+1”and “2+2”circuits, including the thyristors triggering time, the transient capacitor voltage and current during the switch transition. In the end, simple triggering modules are developed for the above two circuits, and their triggering mechanisms are also addressed respectively.
