Design and Performance Analysis of a Reduced-Capacitance H-9 Five-Level Switched-Boost Capacitor Transformer less Inverter

A seven-page technical synthesis of the reduced-capacitance H-9 five-level switched-boost capacitor transformer-less inverter has been presented using the uploaded Aruna documentation. The ideal voltage relations predict a 100 V switched-capacitor voltage and ±200 V peak level at 40 V input and D = 0.6. The supplied simulation figures illustrate input-voltage regulation, current startup, ac waveforms and capacitor behavior. Separately, source-reported prototype measurements describe low leakage currents and 1.29% filtered-voltage THD. Reproduction of these experimental claims requires the original circuit files, control implementation and measurement records.
