Inverter Topology

A novel topology of a hybrid grid connected topology based on photo voltaic system and permanent magnet synchronous generator is proposed in this paper. In this grid connected inverter topology the source are connected to the grid with the help of multi input modified LUO converter followed by a single phase three level inverter. Thus compared to the conventional schemes the proposed topology is modeled with the help of reference frames includes direct axis and quadrature axis elements. The modified LUO converter inherits the advantages compared to other DC-DC to converter topologies. The fuzzy logic based MPPT algorithm shows excellent performance under various testing conditions. The PWM generators are used to trigger the inverter and LUO converter. Steady state and transient response of the controllers are discussed and implement the excellent operation of the hybrid energy system. The grid current synchronization is achieved by using PI controller also it will reduce the THD and satisfies the IEEE harmonics standard.

Inverter Topology

Multilevel inverter (MLI) has become more popular in high power, high voltage industries owing to its high quality output voltage waveform. This paper proposes a novel single phase extendable type MLI topology. The term ‘extendable’ is included since the presented topology can be extended with maximum number of dc voltage sources to synthesize larger output levels. This topology can be operated in both symmetrical and asymmetrical conditions. The major advantages of the proposed inverter topology include minimum switching components, reduced gate driver circuits, less harmonic distortion and reduced switching losses. The comparative analysis based on the number of switches, dc voltage sources and conduction switches between the proposed topology and other existing topologies is presented in this paper. The comparison results show that the proposed inverter topology requires fewer components. The performance of the proposed MLI topology has been analyzed in both symmetrical and asymmetrical conditions. The simulation model is developed using MATLAB/SIMULINK software to verify the performance of the proposed inverter topology and also the feasibility of the presented topology during the symmetrical condition has been validated experimentally.
