The invention provides a digital IGBT (Insulated Gate Bipolar Transistor) series connection voltage-sharing circuit based on a look-up table. The circuit comprises a voltage sampling circuit, an AD (Alternating current-Direct current) conversion circuit, an FPGA (Field Programmable Gate Array) circuit, a DA (Direct current-Alternating current) conversion circuit, and an IGBT (Insulated Gate Bipolar Transistor) driving circuit. The digital IGBT series connection voltage-sharing circuit has the advantages of being quick in voltage-sharing speed, high in precision, and simple in circuit, can comprehensively solve the technical problems of voltage-sharing, over-current and short circuit protection of the series connection, is suitable for IGBT control and protection circuits of high-voltage occasions (based on IGBT series connection) such as soft direct current power transmission, power electronics transformers, high-voltage inverters, active power filters and static var generators.
