Solar eruptions are well-recognized as major drivers of space weather but what causes them remains an open question. Here we show how an eruption is initiated in a non-potential magnetic flux-emerging ...

Figure 1 Schematic diagrams of two superconducting flux qubit circuits. The conventional qubit (a) requires an external magnetic field to operate optimally, while the new flux qubit (b), using a ...

This application note presents space vector control or field-oriented control (FOC) using polar coordinates. It is used for controlling 3-phase alternating current induction motors (ACIM). The ...
