ABSTRACT
In this paper, a new topology of two-stage cascaded switched-diode (CSD) multilevel inverter is proposed for medium voltage renewable strength integration. Firstly, aims to limit the number of switches along with its gate drivers. Thus, the installation space and fee of a multilevel inverter are reduced. The spike removal switch added in the first stage of the inverter gives a flowing direction for the reverse load current, and as a result, excessive voltage spikes going on at the base of the stepped output voltage based upon conventional cascaded switched-diode multilevel inverter topologies are removed. Moreover, to resolve the problems related to DC source fluctuations of multilevel inverter used for renewable power integration, the clock section shifting (CPS) one-cycle control (OCC) is developed to control the two-stage CSD multilevel inverter. By shifting the clock pulse section of every cascaded unit, the staircase-like output voltage waveforms are obtained and a strong suppression capacity against fluctuations in DC sources is achieved.
