FAQ on three-phase AC power part 2: implementation
We’re familiar with single-phase AC at the outlet, but multiphase AC offers advantages and is necessary for higher-power installations. The first part of this article examined the need for three-phase AC. This part looks at the implementation. Power sourcing and wiring Q: How is the three-phase AC power generated? A: It does not use three […]
FAQ on three-phase AC power: part 1
We’re familiar with single-phase AC at the outlet, but multiphase AC offers advantages and is necessary for higher-power installations. For most engineering designs, the circuit’s DC operating power comes from one of two sources: either a battery or a basic AC line, which has been stepped down via a transformer, rectified to DC, and then […]
GaNe-based controller achieves standby power below 30 mW
