Design of an LCC current-output resonant converter for use as a constant current source [PDF]
2007 European Conference on Power Electronics and Applications, 2007 A methodology for the design of LCC resonant current-source converters, is presented. Unlike previous techniques, the resulting converter provides near constant steady-state output current over an extended load range when excited at the resonant frequency, through use of a self-oscillating controller.

An LED Drive Circuit with Constant-Output-Current Control and Constant-Luminance Control [PDF]
An LED Drive Circuit with Constant-Output-Current Control and Constant-Luminance Control, 2006 A Single LED is very small, and their luminance is related to the amount of driving current. Sufficient luminance for an illuminator requires many LEDs to be connected together and a constant current supplied to each LED. Therefore, the LED drive circuit must have constant-output-current control and/or constant-luminance control.

Input-output impact analysis in current or constant prices: does it matter? [PDF]
Journal of Economic Structures, 2012 This paper addresses the question whether the results of input-output (IO) impact analyses differ (and to what extent) when a framework in current prices or in constant prices is used. We consider the effect of an exogenous stimulus of final demand in current prices on (a) gross output in constant prices, and (b) employment. In an empirical application
