This paper proposes a single-stage inverter topology for grid connected PV systems. Isolated voltage generated by the solar modules is effectively used in a neutral point clamped multilevel inverter to generate high quality AC voltage for feeding into the grid. The control scheme is implemented in synchronously rotating reference frame for independent control of active and reactive power. Loss calculation...
Multilevel inverters are commonly modulated by using multicarrier pulse width modulation techniques such as phase-shifted multicarrier modulation and level-shifted multicarrier modulation. However, level-shifted multicarrier modulation technique produces the best harmonic performance than the phase-shifted multicarrier modulation technique. But it is having apparent disadvantages of unequal device...
Summary form only given. A scheme for connecting a marine power plant (MPP) to a distribution grid in local shore is presented. In this scheme, power generated from two wave energy generators based on Archimedes wave swing (AWS) is fed through a combination of DC/DC converter and inverter to the grid. Suitable controls of the DC/DC converter and the inverter are suggested to ascertain satisfactory...
