Multilevel Inverters and Converters

This work proposes a non-isolated single-switch DC-DC converter based on the integration of the classical single-ended inductance converter (SEPIC) and Zeta topologies using the graft technique. The resulting topology can provide high step-down or high step-up depending on the rated duty cycle. It also shows some interesting advantages, that is, both the input and output stage currents are non-pulsating with low ripple, resulting in low electromagnetic interference (EMI) levels. A thorough mathematical analysis is derived, from which it is possible to obtain simulation results aiming at validating the theoretical assumptions.
