Shipboard propulsion, power electronics, and ocean energy by Mukund R. Patel

By Mukund R. Patel

Shipboard Propulsion, energy Electronics, and Ocean Energy fills the necessity for a complete publication that covers smooth shipboard propulsion and the facility electronics and ocean strength applied sciences that force it. With a breadth and intensity no longer present in different books, it examines the facility electronics structures for send propulsion and for extracting ocean strength, that are reflect pictures of every other.

Comprised of 16 chapters, the e-book is split into 4 components:

  • Power Electronics and Motor Drives explains uncomplicated strength electronics converters and variable-frequency drives, cooling tools, and caliber of power
  • Electric Propulsion Technologies specializes in the electrical propulsion of ships utilizing lately constructed everlasting magnet and superconducting vehicles, in addition to hybrid propulsion utilizing gasoline cellphone, photovoltaic, and wind power
  • Renewable Ocean strength Technologies explores renewable ocean strength from waves, marine currents, and offshore wind farms
  • System Integration Aspects discusses aspects―energy garage and procedure reliability―that are crucial for any large-scale strength system

This well timed e-book advanced from the author’s 30 years of labor adventure at common electrical, Lockheed Martin, and Westinghouse electrical and 15 years of training on the U.S. service provider Marine Academy.

As a textbook, it's excellent for an non-compulsory direction at marine and naval academies with engineering courses. it's also a useful reference for advertisement and armed forces shipbuilders, port operators, renewable ocean power builders, category societies, equipment and kit brands, researchers, and others drawn to glossy shipboard strength and propulsion systems.

The info supplied herein doesn't inevitably symbolize the view of the U.S. service provider Marine Academy or the U.S. division of Transportation.

This booklet is a spouse to Shipboard electricity Systems (CRC Press, 2011), via an analogous author.

4: High di/dt causes which: high voltage stress or high current stress? Why? 5: High dv/dt causes which: high voltage stress or high current stress? Why? 6: When would you need to rerate (derate or uprate) the device and for what reason? FURTHER READING Ahmed, A. 1999. Power Electronics for Technology.

Undeland, and W.

Determine (a) the required series rheostat resistance and the process energy efficiency and (b) the switching duty ratio D and the energy efficiency if an ideal power electronics control is employed. 8 V and reverse breakdown voltage of 50 V. 3, determine the average power absorbed by the resistor. 4: A thyristor in a certain 240-V converter design can see a maximum forward voltage of 120 VLNrms. Its data sheet specifies the maximum allowable di/dt of 80 A/μs. Determine the snubber inductor you must include in the converter design to limit di/dt to 60 A/μs to allow for a desired margin.

SOLUTION We first recall that (1) the voltage drop in the diode when it conducts in the forward or reverse direction is independent of the current magnitude, and (2) the power loss in the diode equals the voltage drop in the diode times the current through the diode. In circuit (a), the diode is forward biased (in the conducting direction); hence, it will conduct since the applied voltage exceeds the prospective voltage drop of 1 V. 15 A. 15 W. In circuit (b), the diode is reverse biased with the applied voltage less than the reverse breakdown voltage.
