The invention discloses a solid-state pulse power supply system of a field anti-configuration device and a time sequence control method of the solid-state pulse power supply system. The solid-state pulse power supply system comprises a multiplex load coil, and a bias branch, an ionization branch, an anti-field branch and a steady-state branch which are connected to the two ends of the coil in parallel. A main switch of each branch circuit adopts a solid-state switch element, natural follow current is realized by using a diode or a bidirectional structure in the branch circuit, and an independent follow current branch circuit is thoroughly canceled. Meanwhile, in cooperation with a microsecond time sequence control method, a steady-state branch circuit is conducted in advance to excite the reactor to form virtual impedance, and pure physical series voltage division protection is achieved. According to the invention, full time sequence multiplexing of the coil function is realized, the stray inductance, the size and the cost of the system are reduced, kHz-level repetition frequency operation can be supported, and the reliability and the stability of the field inversion configuration device are obviously improved.
