Along with fossil and nuclear-based power, future energy distribution systems ought to be capable of interconnecting diverse renewable sources, such as hydroelectric generators, photovoltaic arrays, and wind turbines, as well as energy storage systems. The development of “Smart Grid” is needed due to increasing electricity demands and the need regulate input power sources. However, a particular challenge anticipated by a “Smart Grid” is the high variability of the power provided by the renewable sources, mainly due to their high dependence on environmental conditions. In turn this variability imposes a challenge to power conversion in particular, between DC and AC signals. Single-phase DC/AC inverter, using Pulse Width Modulation (PWM) is one of the most common topologies used in power conversion. However, one of the main shortcomings of converters controlled by PWM-based algorithms is that they are not robust to changes in the input DC voltage, which limits their use in renewable energy applications.
