Heat current limiter and constant heat current source
Physical Review E, 2012Current limiters and constant current sources, which play important roles in electronic circuits, have been built up for many decades. Their thermal counterparts, heat current limiters and constant heat current sources, are still not available yet. By combining two typical nonlinear lattices, the Frenkel-Kontorova (FK) lattice and a coupled rotator ...

Review of Scientific Instruments, 1976
When placed in series with a voltage source of 5 V or more, the constant current ballast will pass a preset constant current independent of voltage or resistance variations. Performance and characteristics for a system capable of delivering up to 0.6 A are described.

A Constant Current Digital Control Method for Primary-Side Regulation Active-Clamp Flyback Converter
European Conference on Cognitive Ergonomics, 2020Active-clamp flyback converter is now widely used because higher efficiency is obtained with soft-switching technique. However, opto-coupler is always applied in the feedback loop to acquire the output signal.

Constant current source for iontophoresis
Journal of Neuroscience Methods, 1989A simple, battery-powered current source is described that is suitable for the iontophoresis of axonal tracing substances, such as Phaseolus vulgaris leucoagglutinin. Unlike the previous designs that form the basis of most commonly used iontophoretic devices, this circuit does not use operational amplifiers to provide controlled current.

A Static Constant-Current Circuit
Transactions of the American Institute of Electrical Engineers, 1938Static constant-current circuits have been constructed by connecting an iron-core reactor, with predetermined characteristics, in parallel with a capacitor of a specified size such that the resultant input current is independent of line voltage. This parallel circuit is connected in series with the element through which the current is to be regulated ...
