However, the proposed inverter does experience high-voltage stress on the polarity generation circuit. Based on this comprehensive literature review, there is a conspicuous opportunity to develop new inverter topologies demanding fewer capacitors and components while still achieving high boosting factors.
The method of utilizing switched capacitors stands as an effective approach to achieve elevated voltage levels while minimizing the requirement for numerous DC sources through efficient utilization of stored energy in capacitors.
Therefore, eliminating the need for a two-stage conversion and no need for a complex system to boost the output voltage and balance the capacitor voltage, respectively. Therefore, this single-stage system minimizes the size, reduces cost, decreases complexity, and improves system efficiency.
The switched capacitors C 2 and C 3 are charged to 0.5V dc while capacitor C 1 is charged to V dc by connecting them in parallel with the input voltage source (V dc) in an appropriate manner as presented in Table 1. This improved topology provides redundant states for charging
