This paper presents the design of control module of grid connected photovoltaic system. photovoltaic array is being widely used nowadays. Sun energy could be utilized by the use of photovoltaic systems. But the photovoltaic array output is highly non-linear to be directly connected to the utility grid. Hence the output is applied through DC-DC boost converter. Output of converter is converted to AC using an inverter. Both the converter and the inverter is controlled by the digital control module. Control module generates PWM signals to operate the MOSFET switches of the inverter. PWM signal is in phase with the utility grid voltage. Hence the AC output voltage of the inverter also will be in phase with the grid voltage. Digital controller includes MPPT module and PI controller. MPPT algorithm makes sure that the photovoltaic output is taken at the maximum power point. PI controller stabilizes the output PWM signal. The controller is implemented using dsPIC30f.Tool used is MPLAB. Use of renewable resource makes the project highly attractive.

The study focused on the problems faced by the foreign tourist. For the purpose of analyzing the objective three tourist destinations in Kerala viz., Kovalam beach, Wayanad and Idukki were selected and 30 foreign tourists were surveyed from the three selected tourist destinations using convenience sampling technique. A structured survey schedule was used for interviewing selected tourists and analysis was made with the help of index tool. The study identified that the problems encountered by foreign in Kerala are generally minor problems. However, some of them require particular attention for the improvement of the tourism industry like problems related to legal formalities and enforcement as well as problems related to cleanliness and hygiene which were mentioned to be the most strenuous problems encountered, followed by problems related to food.Keywords

Considering the promising future of on line marketing the study aimed to analyse the determinants and constraints of on line marketing. 120 students (who were engaging in online shopping) selected from two colleges (representing one professional and one traditional college) from Thrissur district consisting of 60 male and 60 female respondents were equally selected and primary survey was conducted through a structured interview schedule. The study highlighted that major factor of online shopping is convenience. Online marketers may pay more attention to free delivery, or free gift and do the best to build, enhance and maintain their good reputation. Delivery in time is an vital factor and important constraint, the proper delivery in time and nearest place it will create trust and image of the websites, therefore, advisable to concentrate on proper delivery services.Keywords
