sure 3-phase would work towards the future, and saves a conductor too, I'm trying to save all consumer equipment (since they universally use 2-phase AC) AND the energy buffer capacitors / inductors in the inverter.
- mikepurvis 7y agoMaybe the real thing here is to get more inductive load equipment shipped with 3-phase as the default. Dryers and stoves are, but they're mostly resistive, and it's for load reasons— 1500W just isn't enough for those applications. But thinking of air conditioners, fridges, washing machines, central vacs, etc; those are all typically shipped today with a two-phase plug but could use 3-phase. OTOH, if they're not actually driving the motor with the 3-phase and are all just rectifying the power and generating their own waveform with a VFD then there's no point; they should have an option to accept DC.
- kragen 7y agoA three-phase circuit consists of three single-phase circuits that share a neutral wire (which, ideally, carries no net current).
- DoctorOetker 7y agotrue, and the 4-phase I propose would also need a neutral for safety... so this advantage for 3-phase persists, as it can do with one conductor less..
