“…The reliability analysis using the Markov approach involves calculating the reliability function, which is the probability that the system will remain in a specified state. Using MIL-HDBK-217F handbook and the equations in [28], the failure rates of the proposed inverter is derived, which is mentioned in TABLE I. According to the mentioned rates, the failure rates of active semiconductor devices in the proposed structure hold a higher total share in comparison with the passive components like inductors and capacitors.…”

Switched capacitor multilevel inverter topologies are attractive among industrial power electronics researchers due to their applicability in sustainable energy systems such as renewable energy source (RES) applications. In this paper, a new switched capacitor (SC)-based grid-tied seven-level inverter is proposed for renewable energy sources (RES) applications. The proposed inverter can generate a seven-level output voltage waveform with voltage boosting ability and a gain factor of 3. Also, the proposed topology can provide the self voltage balancing for capacitors. The most important challenge of the SC-based topologies, i.e., the capacitor charging spike current, is solved by applying a soft charging circuit in the charging loop of the capacitors. The soft charging circuit consists of an inductor and a power diode in the capacitor charging path. Using a small size inductor in the soft charging circuit, the proposed inverter can limit the input current spikes. Comprehensive experiment results and comparisons are presented to verify the accurate performance of the proposed inverter.

“…The Markov strategy is the most well-known method for assessing the reliability of power systems. This method can be used if the system behaviour is determined based on memory shortage [56,57]. The Markov chain is described as a finite class of random processes {X n } with finite state space S if for any positive integers k, n (k ≤ n), and any choice of modes i 0 , …, i n+1 in S. Therefore, the Markov equation can be written as follows:…”

Due to serious Concerns such as air pollution, global warming, and fossil fuels shortcoming, renewable energy sources such as photovoltaic applications are dramatically being integrated into the power generation systems all of the world. Here, a new switched‐capacitor‐based transformer‐less grid‐tied inverter has been proposed. By applying the series–parallel switching technique of the utilized switched‐capacitor module, the voltage boosting capability has been obtained. By implementing common ground technique, high overall efficiency and leakage current elimination capability have been obtained. Since the proposed inverter provides a multi‐level output voltage, the total harmonic distortion of the injected grid current is reduced. The introduced control strategy has been implemented to control both active and reactive powers and generate the switches pulses. Therefore, a high quality and adjusted current is injected to the grid. This inverter requires a single renewable energy source as input DC source. Here, the comprehensive description of the proposed inverter and its performance with design considerations have been presented. The proposed structure has been compared with several similar structures and the obtained results have been investigated. To evaluate the performance of the proposed inverter, a 620 W laboratory prototype is assembled and experimental results are analyzed.
