The invention relates to an efficient
coupling energy taking based high-
voltage TSC driving device, belongs to the technical field of high-
voltage TSC driving, and aims to solve problems such as poor isolation intensity and poor anti-interference ability of a high-
voltage TSC driving device at present. The efficient
coupling energy taking based high-voltage TSC driving device comprises a
signal conditioning module, a control module, an
optical fiber transmission module, a DC power supply circuit, a
coupling energy taking circuit and a TSC
driving circuit, and is characterized in that three-phase voltage and three-phase current at a load side of a power distribution network are inputted into the
signal conditioning module, voltage and current signals outputted by the
signal conditioning module are transmitted to the control module, switching signals outputted by the control module are transmitted to each
thyristor driving board of the TSC
driving circuit through an output end of the
optical fiber transmission module; high-frequency output of the DC power supply circuit is transmitted to the coupling energy taking circuit, and the coupling energy taking circuit provides a working power supply for each
thyristor driving board of the TSC
driving circuit; and the
thyristor driving boards output driving signals to gate poles of thyristors according to zero-cross detection signals and the switching signals of the corresponding thyristors. The efficient coupling energy taking based high-voltage TSC driving device is used for driving high-voltage thyristors.
