The power generated by a Photovoltaic(PV) cell depends on the operating voltage of the array, its voltage-current and voltage-power characteristic curves specify a unique operating point at which maximum possible power is delivered and the array is operated at its highest efficiency. PSCAD/EMTDC, which is a simulation tool for the transient analysis of an electric power system, was used to simulate the PV Cell system. So, in this paper, the PV cell components of the PSCAD/EMTDC were developed, and the Maximum Power Point Tracking(MPPT) modeling was used for the developed PV power system to find the maximum power.

This paper shows a new kind of push-pull switching converter for fuel-cell system and analyses the connected characteristics of it. In these characteristics, we are concerned about the high harmonic rate of output current, we also have designed the filter system for the inverter. Besides, the characteristics should be certified better if the ripple of the fuel-cell output current has been eliminated.

The study on the multi-level inverter has been increasingly progressing to reduce the switching loss and improve the THD of output current in photovoltaic inverter. Recently, the main topics of multi-level inverter are to reduce the number of devices maintaining the power quality. Therefore, the novel topology was proposed for these problem which is composed of the isolated H-bridge multi-level inverter using the three phase low frequency transformer. The proposed multi-level inverter may not be need for a independent DC power, diode and capacitor. Specially, It has a advantage in generating high voltage source. The proposed approach is verified through simulation and experiment.
