In this paper, two new cascaded inverters are proposed, by using the series connection of new Submultilevel inverters. Each of the proposed Submultilevel inverters consists of three batteries and eight power switches. Four algorithms are presented to determine the voltages of these batteries for each of the proposed structures. In this study the comparison between the proposed structures with c...

Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...

Valves are integral parts of modern steam turbines. They provide flexible operations and fast load changes which have become more often due to the increasing share renewable energy. Along with this, low pressure loss is required for guaranteed operation conditions. This paper concerned investigation losses in compact valve, used as a valve intermediate-pressure turbine part, its geometry modifi...
