Design of Digital Current Mode Controller for Active Clamp Forward Converter

ABSTRACT With the rapid development of Microprocessors/Microcontrollers digital controllers are becoming viable one as compared to conventional controllers. To overcome the drawbacks in single loop simple Voltage Mode Controllers and improve the performance of the converter, two loop current mode Controllers need to be designed. This paper presents the step by step design procedure to […]

Multi Criteria Decision Making Tools for Supplier Evaluation and Selection: A Review

ABSTRACT In competitive markets, companies are always under intense pressure to find ways to reduce production and material costs to survive and sustain their competitive position in their respective markets. Since a qualified supplier is a vital element for a buyer in reducing such costs, evaluation and selection of the potential suppliers has become an […]

Discrimination between Conventional and Modified P&O Algorithm for Solar PV Cell Application Using MATLAB

ABSTRACT This paper deals with the discrimination analysis between conventional and modified perturb and observe algorithm for solar PV cell. Basically perturb and observe algorithm is the most widely used algorithm because it contains less maintenance and less complexity. But due to sudden change in weather conditions this algorithm cannot work properly and efficiency reduces. […]

Securing Pervasive Communications in Healthcare Systems

ABSTRACT Current healthcare and wellness monitoring devices make medical follow-up convenient. However, the decentralization of data processing and extensive reliance on network connectivity introduces security threats. Current smart health devices often focus their attention more on usability and design rather than solidifying underlying security measures. While web-based security is available, device-level security in smart health […]

Keyword Extraction Mechanism for Efficient Document Recommendation: A Review

ABSTRACT Document recommendation system is useful to find the right results immediately without adding filters manually or clicking through multiple navigation menus. This paper first surveys various just in time retrieval agent and then reports several term weighting scheme. Just in time retrieval agent proactively provides valuable information without any explicit search. Term weighting enriches […]

Effect of Substrate Material on the Electrical Properties of HfO2 MOS Device

ABSTRACT Hafnium oxide (HfO2) films were grown by atomic layer deposition on chemically cleaned p-type Ge and Si substrates with different thicknesses. For the electrical measurements, we fabricated the metal-oxide-semiconductor (MOS) devices with Platinum (Pt) electrode. The capacitance-voltage and current-voltage characteristics were measured on the sandwich structure of Pt/HfO2/substrate. From the C-V measurement and we […]

A Taxonomical Review on Distributed Generation Planning

ABSTRACT This paper presents a taxonomical review on Distributed Generation (DG) planning in the distribution power network from different power system performances such as minimization of real and reactive power loss, enhance power system load ability, enhance power system stability, enhance power system reliability, enhance power system security, enhance available power transfer capacity, enhance power […]
