Among multilevel inverter topologies, asymmetric Cascaded H-Bridge (CHB) inverters have higher output-voltage levels than symmetrical ones. However, asymmetric multilevel inverters need pre-stage isolated and floating DC power sources, which make the system complicated and bulky. This paper is focused on solving the problem by using a single-core (magnetically-coupled) multiple-output forward-f...

Renewable energy, such as solar energy, is desirable for power generation due to their unlimited existence and environmental friendly nature. Reforming of the electricity sector along with various renewable energy promotion policies has increased the importance of small grid connected photovoltaic (PV) systems utilizing single stage single phase inverters. This paper proposes a single-stage inv...

This paper proposes a single stage solar power generation with boost dc-ac inverter by simple control technique. The boost dc-ac inverter converts and boosts a low output dc voltage of the solar pv array into a 220Vrms ac voltage at a fundamental frequency of 50Hz in single stage. A simple Modified Non-Linear State Variable Structure (MNLSVS) closed loop control technique is proposed to keep th...

This paper, proposes an analysis and design of a high efficiency boost-inverter with bidirectional back-up battery storage in fuel cell. When low-voltage unregulated fuel cell (FC) output is conditioned to generate AC power, two stages are required: a boost stage and an inversion one. In this paper, the boost-inverter topology that achieves both boosting and inversion functions in a single-stag...

Multilevel inverter becomes popular because of its high power, high voltage application. However it has some disadvantages such as increased number of components, complex control method and voltage balancing problems. In this paper, we proposed a new topology having level modules and H-bridge inverter, and reverse voltage technique is adopted for load. APOD based PWM technique is used to genera...

The Flying Capacitor Multi Level Inverter (FCMLI) has a great advantage with respect to the availability of voltage redundancies. This work proposes a switching pattern for a modified inverter structure. It is used to improve the performance of chosen single phase five level H-bridge type FCMLI as compared to conventional FCMLI. The chosen multi level inverter is simulated for various multicarr...
