Implementation of Nine-Switch converter to PV solar array operating with different loads

Solar energy is a non-depleting source of energy where one hour of solar energy reaching on earth's sur -face is enough to meet the world's demand for a year. In present scenario people need electric power every single minute. Solar energy can be easily generated using photovoltaic panels for any type of pur -poses i.e., domestic or industrial. It is also very efficient and clean energy system. A lot of researches are going on solar energy to make it more efficient so that maximum energy can be drawn from sunlight. Conversion of solar energy to electrical energy includes a number of converters according to its use. One major issue related to a converter is with respect to switching losses, on state losses and sometimes complex gate circuits. Primarily from few years a lot of emphasis is given to reduce the number of switches in a converter circuit. Nine Switch Converters are a major leap in the world-changing scenario towards the converters that are being employed to the various systems, due to its various advantages which include fewer switching devices than usual, less switching losses and high-power quality. In this paper, a Photovoltaic solar array is used as a source along with a Nine-Switch converter to power a sep-arate three-phase load. The voltage generated by the Photovoltaic solar array is regulated using a dc-dc boost converter whose output is supplied to the input of the nine-switch converter that will ultimately power the loads. The gating signals for the nine-switch converter employs the space vector modulation technique, as space vector modulation has a number of advantages when compared to other modulation techniques which includes less harmonics, higher modulation index etc. A MATLAB simulation is included to show the performance of the system.
