The paper suggests the use of supercapacitors in the bridge crane AC drives application, as storage auxiliary device connected in parallel with the main power source for energy saving. A sizing procedure is proposed. The design procedure of the storage system is derived from theoretical considerations. It leads to evaluate the ratings of all devices capable of satisfying the load requirements. Numerical results are reported in order to show the feasibility of proposed technical solution and to evaluate the energy saving.

Abstract
The paper suggests the use of supercapacitors in the bridge crane AC drives application, as storage auxiliary device connected in parallel with the main power source for energy saving. A sizing procedure is proposed. The design procedure of the storage system is derived from theoretical considerations. It leads to evaluate the ratings of all devices capable of satisfying the load requirements. Numerical results are reported in order to show the feasibility of proposed technical solution and to evaluate the energy saving.File in questo prodotto:
