This article reports the modeling of the parallel connection of multiple piezoelectric oscillators with respective electrical rectification. Such an array structure offers advantages of boosting power output and exhibiting broadband energy harvesting. The theoretical estimates are proposed for different choices of electronic interfaces, including the standard and parallel-/series-SSHI (synchronized switch harvesting on inductor) circuits. It is shown that the electrical response is governed by a set of simultaneous nonlinear equations with constraints indicating blocking by rectifiers. Finally, the validation is carried out by circuit simulations and shows good agreement.
