Title:

THYRISTOR DRIVE APPARATUS

Document Type and Number:

WIPO Patent Application WO/2016/134669

Kind Code:

A1

Abstract:

A thyristor drive apparatus suitable for driving a thyristor in an alternating current electric grid, comprising a non-isolated power supply circuit (A) and a throttle circuit (B), one end (J1) of a power source input end of the non-isolated power supply circuit (A) being used for connecting to a first end of the thyristor to be driven, another end (J4) of the power source input end being used for connecting to another phase of the power source relative to the first end or to a neutral wire, the non-isolated power supply circuit (A), by means of the throttle circuit (B) and the second end and first end of the thyristor, forming a trigger signal loop, a control end of the throttle circuit (B) being used for connecting to a third end of the thyristor, the present thyristor drive apparatus having the advantages of occupying minimal space, a simple circuit, a large instant trigger current, and low energy consumption.
