In the work, through analytical considerations, the peak efficiency of three different variants of galloping energy harvester was defined. For this purpose, the authorial method based on elliptic harmonic balance was employed, consisting of comparison of impossible to analyze, accurate high order solutions, and simplified solutions of a linearized model. Research has shown that the peak efficiency of the hardening and bistable devices is greater by 17% and 30% respectively in regards to the linear device, while application of softening stiffness always leads to a loss of efficiency.
