**5. Conclusions**

This paper proposed a modified high output gain Cuk converter with an SMC-based equivalent ´ controller. The efficiency and performance of a classical Cuk converter was improved by the simple ´ inclusion of a single inductor and capacitor. Moreover, a constant switching frequency cascaded equivalent controller structure is proposed. Simulation results show the effectiveness and robustness of the proposed method, and the constant switching frequency approach to the SMC-based controller provides the opportunity of simple application to real systems.
