Careful selection of key components and the use of straightforward multiplication schemes can be applied to the design of a low-noise frequency synthesizer for Ku-band signals to 20 GHz.


Control Of A High-Performance Z-Source Inverter For Fuel Cell/Supercapacitor Hybrid Electric Vehicles, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire Dec 2010

Control Of A High-Performance Z-Source Inverter For Fuel Cell/Supercapacitor Hybrid Electric Vehicles, Omar Ellabban, Joeri Van Mierlo, Philippe Lataire

Omar Ellabban

This paper presents a supercapacitor (SC) module connected in parallel with fuel cell (FC) stack to supply a high-performance Z-Source Inverter (HP-ZSI) feeding a three phase induction motor for hybrid electric vehicles applications. The supercapacitor is connected between the input diode and the bidirectional switch of the highperformance ZSI topology. The indirect field-oriented control (IFOC) method is used to control an induction motor speed during motoring and regenerative braking operations to produce the modulation index and a dual loop controller is used to control the Z-network capacitor voltage to produce the shoot-through duty ratio. MATLAB simulation results verified the validity …

Application Of Electromagnetic Waves As A Solution To Some Agricultural Problems, B. M. Ida Idayu, Maryam Ashayer Soltani, Amin Enayati, H. Aliakbarian, Hossein Ameri Mahabadi, M. Moghawemi Jan 2010

Application Of Electromagnetic Waves As A Solution To Some Agricultural Problems, B. M. Ida Idayu, Maryam Ashayer Soltani, Amin Enayati, H. Aliakbarian, Hossein Ameri Mahabadi, M. Moghawemi

Hossein Ameri Mahabadi

A review of some applications of electromagnetic waves in agriculture is presented. There are many applications in the literature which are categorized in two sections of post-harvest indoor and pre-harvest outdoor applications. Taking a look at the applications suggested, there are still works to be done to industrialize the method. However, the proposed method is promising in special cases when the cost and hazards of other methods are high.
