Abstract-Inverters with reduced number of switches have been proposed in the literature to improve the capability of cost reduction, total inverters size and switching losses of dc/ac inverter topologies. In addition, they have a lower probability of damaging the semi-conductor switches as well as lower commonmode currents. This paper proposes new designs for inverters with reduced number of switches. For three-phase systems, the proposed inverters use four switches instead of six in the traditional three-phase Voltage Source Inverter (VSI). Compared to the traditional Four-switch three-phase (FSTP) inverter, the proposed FSTP inverters improve the voltage utilization factor of the input dc supply. Classical controllers as well as sliding mode controller are used to discuss the dynamic response and robustness of the inverters. In addition, the paper presents new single-phase inverters with two switches instead of four in the traditional VSI. The capability of suppressing the 2 nd order current harmonic from the input dc side is discussed. Equations explaining the control design, switches ratings, and the operation of the proposed inverters are presented in this paper. The basic structure, control design, and MATLAB/SIMULINK results are presented. Practical results substantiate the design flexibility of the proposed topologies when controlled by a TMSF280335 DSP.

The Photovoltaic standalone system is gaining its high importance mostly for rural application like pv water pumping, solar lighting, battery charging etc.Considering environmental effects and scarcity of fossil fuel the trend has developed towards the use of more and more renewable energy.In this paper a basic circuit of boost converter is designed in MATLAB/Simulink with constant dc source voltage. However a comparative study has also been done for the converter connected with pv system directly with the converter connected with mppt tracking technique. Perturb and Observance (P&O) algorithm is implemented for providing the necessary duty pulse and makes the system operate at maximum power point.The boost converter connected with PV system without mppt operates at any other point other then the maximum power point and hence the output voltage decreases.But with mppt the proposed system performs better.

“…It uses the capacitor for energy transfer, while other converters such as buck and boost converters use the inductor to do it [1]. Moreover, the Cuk converter has continuous voltage and current at both input and output terminals, thereby keeping the number of components and the component size small [5]. Cuk converters are widely used in industries such as wind energy [2], photovoltaic power system [3], [5], electrical vehicle [4] and fuel cell charger [6].…”

A integral sliding mode controller (ISMC) for a fixed-frequency PWM is proposed for the Cuk converter. The fourth-order model of the Cuk converter is derived first and it is simplified to use ISMC. Based on the simplified system model, the ISMC that consists of the equivalent control part plus the switching control part is designed and applied to the Cuk converter in the presence of uncertain variations and unknown disturbances. The closed-loop system is also proved to be exponentially stable. Simulation and experimental tests using the prototype of digitally controlled DC-DC converter were performed to validate the proposed control approach.
