Logic processing device and method for switching signals of three-level inverter circuit

The embodiment of the invention provides a logic processing device and method for switching signals of a three-level inverter circuit, and belongs to the technical field of three-level inverter circuits. The device comprises a microprocessor used for sending a first two-dimensional vector to an inner and outer tube switching sequence logic processing unit; the inner and outer tube switching sequence logic processing unit is used for adjusting the jumped first two-dimensional vector according to inner and outer tube switching logic to obtain a second two-dimensional vector if the first two-dimensional vector jumps; the narrow pulse logic processing unit is used for adjusting the second two-dimensional vector according to narrow pulse logic to obtain a third two-dimensional vector; and the decoding and dead-zone logic processing unit is used for adjusting the jumped third two-dimensional vector according to dead-zone logic to obtain an adjusted third two-dimensional vector if the third two-dimensional vector ju
