Popis: The single-phase split-source inverter is an emerging and attractive topology for boost dc-ac power conversion system. Such an inverter features high compactness, however, at the expense of high-frequency commutations across diodes. The corresponding hybrid PWM also confines the voltage harmonics to concentrate around the switching frequency and its multiples. This paper proposes a simplified split-source inverter which is realized by inserting only one power switch into an H-bridge. While generating the ac output, the newly developed PWM strategy ensures the inductor charged with constant duty-cycle. When compared to the existing split-source inverters, it offers the added benefits of reduced switch count, enhanced voltage boosting gain, reduced output filter requirement, and enhanced power efficiency. Comprehensive steady-state analysis is discussed while simulation and experimental results are subsequently presented to prove the validity of the proposed topology and the PWM strategy.
