Abstract

Every solar energy harvester systems have got two sources of energy loss: the MPPT circuit and the dc–dc converter. To increase the efficiency of the PV energy harvester, the energy losses from the MPPT circuit and the dc–dc converter need to be minimized. Here a new MPPT algorithm called successive approximation register is introduced. This MPPT algorithm has got a power down mode and a fast tracking time, to achieve low power consumption and energy savings. With this MPPT algorithm energy losses from the MPPT circuit can be minimized and this technique can be greatly applicable to low power application systems mainly as well as for high power application.DOI:http://dx.doi.org/10.11591/ijece.v4i2.4557

Abstract

A simple PI control loop for the matrix converter system is designed in the simulation to maintain a constant output voltage inspite of any disturbance in the source. The single phase matrix converter employs a modified safe-commutation strategy, which results in the elimination of voltage spikes on switches, without the need of a snubber circuit when there is an inductive load being utilized. This is facilitated through the proper switching control algorithm. The sine PWM pulses are generated as switching pulses to the converter to reduce the THD.DOI: http://dx.doi.org/10.11591/ijpeds.v5i1.5340

Abstract

Industrial automation is largely based on PLC-based control systems. They are used to monitor and control a plant or equipment in industries such as water and waste control, energy, oil and gas refining and transportation. Automation also increases product quality, productivity and decreases breakdown. Conventional equipments or systems are prone to errors due to involvement of humans for data collection and processing using complicated mathematical expressions. Computer integrated manufacturing, computer numerical control; robots, flexible manufacturing system, automated inspection and process control are directing the technology toward one goal, the fully automated factory of the future. Coming to Induction motors, in the conventional case due to long use of a particular induction motor in oil rig related plants more mechanical faults arise due to overheating and may lead to failure which affects production. In case of using two or more induction motors and automating the duty cycle shifting using PLC, the effectiveness of the system increases. Also in case of tripping of a particular motor, other idle motors backs up the operation thereby preventing the plant to go to standstill, hence increasing the overall plant efficiency.

Abstract

It is very much important to have an improved meathod of poultry incubation because of the increase in demand for chicken. But in conventional meathod of poultry incubation it consumes much power and this power is taken from the grid. In short conventional meathod of egg hatching requires countioous supply of power. Weknow about the increasing demand   In this paper a new meathod of solar poultry incubator design is suggested which could be used to hatch eggs from solar pv and hence could reduce the usage of power and can maximize the usage of solar power which is a renewable source of energy.By implementing this meathod of solar poultry incubator we will be able to reduce the power consumption of the incubator by 75% and the cost involved in the design also yields profit and hence could bring out a reveloution in this field.
