This was a breakthrough at the time, though still far from an ideal switch. The Thyristor followed, offering bi-directionality in terms of voltage but not current. Then came the Triac ... with a ...

In an initial test, this circuit was able to efficiently convert AC currents into DC signals at liquid helium temperatures (e.g., those attained using closed-cycle refrigeration techniques).

Littelfuse, Inc. announced the expanded offering to the industrial Solid-State Relays (SSRs) family of products. The ...

Abstract: It is well known that the ac–dc power factor correction (PFC) boost preregulator can present instability at the line frequency. This nonlinear phenomenon can jeopardize the system ...

With rapid growth of power demand, transmission capacity is also in urgent need of upgrading. In some cases, converting existing AC transmission lines to DC lines can Improve the transmission capacity ...

The modulation strategy consists in duty ratio and phase-shift control under a high and fixed switching frequency, which allows high power density. Unlike existing structures, duty ratio control is ...

We investigate how normal movement is produced by neural circuits, and how disruption to these circuits in disease impairs movement. Our goal is to lay foundations for new strategies aimed at ...

We are looking for participants with persistent anxiety who are registered to undergo psychological therapy for anxiety to take part in our research study on the effects of psychological therapy on ...
