Today, regarding the increase in using renewable energy resources, DC/DC boost converters have become more popular than in the past, in particular, the multilevel DC/DC boost converter due to its high voltage gain and simple components to implement. However, the constant power loads (CPLs) are contributed to instability in these converters because of the intense non-linear nature of CPLs.
This paper intends to address this issue by applying a new method based on a combination of the Nonlinear Integral-Backstepping technique (NIB) and Model-Free Control (MFC) to a DC/DC multilevel boost converter (MBC) in presence of a non-ideal CPL. To validate the effectiveness of the proposed controller theoretical analysis and simulation results are represented.
