Evolutionary design of inverter circuit topology based on genetic programming

Optimization design of analog circuit is always subjected to the designer's experience, and has not been a systematic and theoretical approach so far. The use of genetic programming for circuit topology optimization design is always seen in continuous circuit, such as analog filter circuit, etc. The inverter circuit contains many nonlinear hybrid switches. The physical topology and operation have strict requirements. The triode must be symmetrical and paired on and off. It is hard to achieve a complete automation design by computer. Based on the characteristics of inverter circuit, the genetic programming was applied into inverter hybrid circuit designing, and a systematic method of inverter optimization design was carried out. In addition, Matlab/Simulink command line simulation technology was used to avoid the program interface problem, and improve the simulation speed. Finally, a five-level inverter was generated which verified the validity of the method proposed.
