Abstract: Space vector modulation (SVM) technique for CSC is established by dividing ac-side line current cycle into six sectors. Each sector is divided into certain number of space vector (SV) cycles. SV cycle is divided into three states, two active and one zero state. SVM technique generates fifth and seventh harmonics (HD5-7) in the CSC ac-side current when operated with low switching frequencies, i.e., low number of SV cycles. Minimal reduction in HD5-7 was achieved by using certain states sequence inside SV cycle, and by calculating states ON times at once in the middle of each SV cycle. In this paper, fuzzy logic-dependent technique for calculating states ON times in SVM-CSC is proposed.

Abstract: In the present experimental work a computerized Single cylinder Petrol engine with data acquisition system was used to study the effects of oxygen enriched air intake on combustion parameters. Increasing the oxygen content with the air leads to faster burn rates and the ability to burn more fuel at the same stoichiometry. Added oxygen in the combustion air leads to shorter ignition delays and offers more potential for burning Petrol. Oxyfuel combustion reduces the volume of flue gases and reduces the effects of greenhouse effect also. Engine test has been carried out in the above said engine for different loads and the following combustion parameters like Ignition delay, Combustion duration, Heat release and Cylinder pressure was discussed. The research on efficiency has become essential due to depletion of petroleum products and the major contribution of inlet air for the AIRFUEL mixture. In the present work, Oxygen gas is used as the inlet air to overcome the above problems. Of the higher compression ratio, the Oxygen will burn completely and the efficiency of the engine is to be increased. The emission of engine is also to be controlled by using the Oxygen as the inlet air. In this work experimental investigations have been carried out to the engine and the efficiency of the engine is to be compared with the inlet air of atmosphere and exhaust emissions of a single cylinder 4-stroke engine is to verified with the existing engine. For improve the efficiency of the four stroke engine, this process is carried out completely. The thermodynamic analysis of the actual four-stroke or two-stroke cycles is not a simple task. However, the analysis can be simplified significantly if air standard assumptions are utilized. The resulting cycle, which closely resembles the actual operating conditions. In fuel, the tendency for the compressed fuel mixture to ignite early is limited by the chemical composition of the fuel. There are several grades of fuel to accommodate differing performance levels of engines. The fuel is altered to change its self-ignition temperature. There are several ways to do this. As engines are designed with higher compression ratios the result is that pre-ignition is much more likely to occur since the fuel mixture is compressed to a higher temperature prior to deliberate ignition.
