Inverting Modified CUK Converter with Switched Inductor (MCCSI) configurations are articulated in the paper for high-voltage and low-current renewable energy applications. Based on the Switched Inductor (SI) position in ...
Nonlinear stochastic drillstrings vibrations: Parametric study for stick-slip suppression
(
Institute of Physics Publishing
, 2018 , Conference Paper)
Unstable vibrations caused by the transition between static and kinetic frictions produces stick-slip motions which is one of the primary causes of poor drilling efficiency and mechanism failure in the drilling process. ...
Modified transformerless dual buck inverter with improved lifetime for PV applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The Dual Buck Inverter (DBI) possesses no shoot-through concerns and it can improve the efficiency by utilizing power MOSFETs. This is because at accidentally triggered shoot-through states; two inductors are in-parallel ...
