Coconut dehusker machine [PDF]

, 2017
Generally, coconut is dehusked manually using either a machete or a spike. These methods required skill labor and tiring to use. Attempts made so far in development of dehusking tools have been only partially successful and not effective in replacing ...

Pseudo-optimal five-level DCC modulation based on machine learning

International Journal of Electrical Power & Energy Systems
This paper presents a method for the control design of five-level DCC converters based on mixed-integer optimization and machine learning. The resulting controller is computationally simple and can be easily implemented on low-resource control hardware ...

Pwm control of dual diode-clamped converters for PV installation

, 2015
Modulation processes have been analyzed in transformer-based photovoltaic system on the basis of cascaded diode-clamped inverters, adjusted by special control scheme with the use of specific voltage vectors. It has been shown, that symbiosis of this control scheme with algorithms of synchronous modulation insures minimization of common-mode voltage and

Fault-Tolerant Performance Analysis of a Modified Neutral-Point-Clamped Asymmetric Half-Bridge Converter for an In-Wheel Switched Reluctance Motor

Eng
Reliability is an essential factor for the operation of the Switched Reluctance Motor (SRM) drive. Electric vehicles operate in harsh environments, which may degrade the operation of power converters.

A new configuration for multilevel converters with diode clamped topology

, 2008
Due to the increased use of renewable energy and power elctronic applications, more multilevel converters (MLC) are developed. A Neutral Point Clamped (NPC) inverter is one of the most used multilevel topologies for wind turbine (WT) and photovoltaic (PV) applications. One of the most crucial points in this type of converter is dc-voltage control.

A Snubber Circuit With Clamped Energy Feedback for SiC MOSFETs in Hybrid ANPC Converter

IEEE Access
In active neutral-point clamped (ANPC) converters using wide bandgap devices, high switching speeds and inevitable loop parasitics cause voltage overshoot and oscillations during commutation, reducing reliability.
