Abstract Cavitation inside a torque converter induces noise, vibration and even failure, these effects have been disregarded in previous design processes. However, modern applications require attention to this issue because of its high-speed high-capacity requirements. Therefore, study investigated the cavitation effect on using both numerical experimental methods with an emphasis influence cha...

In order to improve reliability of wind turbines, it is important to detect faults in the turbine as fast as possible to handle them in an optimal way. An important component in modern wind turbines is the converter, which for a wind turbine control point-of-view normally provides the torque acting on the wind turbine generator, as well as measurement of this torque. In this paper an unknown in...

AVL Powertrain Engineering, Inc. (AVL) is an independent company specializing in the development of powertrain systems, simulation methods, and engine instrumentation and test systems. The vehicle simulation software Cruise, developed by AVL, is commonly used by automotive original equipment manufacturers to aid in powertrain development (Mayer, 2008). Cruise simulates vehicle-driving performan...

The control of a permanent magnet synchronous generator (PMSG) drive can be achieved through the implementation of different control techniques. This paper presents a comparative study of vector control and direct control techniques applied to PMSG drives for wind turbine applications. Rotor field oriented control (RFOC) and direct torque control (DTC) are considered for the generator-side conv...

A simplified dynamic model for fuel cells is developed, based on the concept of instantaneous characteristic, which is the set of values of current and voltage that a fuel cell can reach instantaneously. This is used to derive a theorem that indicates the conditions under which the power output of fuel cells can, in theory, be perfectly controlled. A fuel cell connected to a DC/DC converter is ...
