Circuit Topology and Operation of a Step-Up Multilevel Inverter With a Single DC Source

 Circuit Topology and Operation of a Step-Up Multilevel Inverter With a Single DC Source

 An attempt to present a multilevel inverter based on a modular structure with a single dc source. This inverter is a switched-capacitor topology, which controls the charging as well as the discharging of the capacitors in the predetermined time intervals. The most important attribute of this multistage structure is the multiple charging capacities of the capacitors at each stage compared with those of the previous stages, which can ultimately increase the output voltage of the low input dc voltage source.
