Our hacker [John Duffy] wrote in to let us know about a video he put together to explain the design of his open-source multimeter, the HydraMeter. If you’re interested in how the circuitry ...

This paper proposes a novel multi-layer coreless printed circuit board (PCB) axial flux magnetic resonant motor (PAFMRM). The PAFMRM transfers electrical energy between the stator and rotor through ...

In this paper, a critical point of the switching loop of a synchronous power converter with Gallium Nitride (GaN) switching devices is investigated. Printed Circuit Board (PCB) designs are proposed to ...
