Nonlinear behavior and mode coupling in spin transfer nano-oscillators

open access: yes, 2014
By investigating thoroughly the tunable behavior of coupled modes, we highlight how it provides new means to handle the properties of spin transfer nano-oscillators.

Optically isolated logarithmic nanoammeter capable of floating to 5 kilovolts [PDF]

open access: yes
A logarithmic current-measuring instrument was developed to measure plasma coupling currents at a common mode voltage of 5 kilovolts. Positive or negative currents can be measured from 10 to the -9th power to .001 ampere direct current. Optical isolation

Input current control of boost converters using current-mode controller integrated with linear quadratic regulator [PDF]

open access: yes, 2012
The application of power electronic converter in the renewable energy systems significantly increases their efficiencies by maintaining the operation of these systems at the optimal operating points, therefore, absorbing the maximum available power from ...

Fast control technique for high frequency (5MHz) DC/DC integrated converter [PDF]

open access: yes, 2010
A switching frequency of 5 MHz allows the integration in a chip of a low power (10W) DC/DC converter. Although this switching frequency would make feasible a voltage mode control with 1MHz bandwidth, the parasitics and robustness don't allow such a high ...

Smart motor technology [PDF]

open access: yes, 1984
Current spacecraft design relies upon microprocessor control; however, motors usually require extensive additional electronic circuitry to interface with these microprocessor controls.
