Energy conservation is a crucial criterion in any industry. Generally, the process industry employs induction motors for its robustness and reliability. Engaging star-delta scheme based energy conservation for induction motors is a conventional practice in process industries. Although the star delta scheme provides economic benefits, it affects the outgrowth of the industries during electrical perturbations...
Pressure switches are the most important entities used in the process industry. A pressure switch is an instrument designed to have a switching action on the process pressure. This paper gives a detailed study and analysis of the pressure switch. This article also throws some light on various kinds of routine and type tests performed on the pressure switch, to ensure the proper functioning of the...
Differential-mode Ćuk inverter (DMCI) represents a class of single-stage inverter with low device count, modular symmetry, and topological simplicity. Recently, discontinuous modulation scheme (DMS) has been proposed for the DMCI. This paper extends the modular nature of the power stage to the control architecture and proposes a transformation-based tracking controller using adaptive control algorithm...
A single-stage differential-mode current-fed zero-current-switching inverter has been designed. This inverter has two modules of dc/dc converters that are connected differentially to the input source. This inverter does not require 60-Hz transformer, front-end dc/dc converter, and can boost a low-voltage input to ac output using a compact low-turns-ratio transformer because of the added voltage gain...
Recently, the operation of a new class of three-phase differential-mode inverter have been proposed and their efficacy demonstrated using a discontinuous-modulation-scheme (DMS) based differential-mode Ćuk inverter (DMCI). DMS-based DMCI has a completely-modular topological configuration. To extend this modularity of the power stage to control implementation, one has to deal with the nonlinearity...
Emerging market of RFSOI applications has motivated us to come up with the robust compact model for RFSOI MOSFETs. In this work, we have validated the RF capabilities of BSIM-IMG model which is the latest industry standard compact model for independent double gate MOSFETs. Results are validated with the experimental S-parameter data measured. Model shows good agreement for different biases over wide...
Source follower based open loop track and hold circuits are commonly employed at front end of pipelined analog to digital converters. Performance of such track and hold degrades at higher operating frequencies due to non linearity arising due to non ideal MOS switches. In present work, conventional open loop track and hold circuit is implemented and its performance is improved by adopting two switch...
