Abstract:

Switched capacitor topologies provide a path towards elevated voltage outputs via the stored energy of capacitors without the need for multiple DC power supplies. The article proposes a new triple boost inverter topology, which is optimized to increase the voltage output while keeping the component count small in order to be applied in renewable energy applications. The Seven-Level SC Triple Boost Inverter (SL-SCTBI) operates with a single DC source with a voltage gain of three times higher than the input with the help of only 8 switches, two diodes and two capacitors. Reduction in its component count and system complexity contributes to higher efficiency and general practicality. A comprehensive comparison study that includes a number of elements, including the number of power electronic devices, gate driver circuits, and capacitors, is described. Since the voltage stabilization occurs at the inverter node, the use of self-balancing capacitors enables circuitry-free stabilization. Comprehensive simulations and laboratory experiments of the SL-SCTBI performance are presented to assess the functionality and effectiveness.
