Square wave outdoor power supply

Which power supply is best for insulating layers?

Since the introduction of dual-magnetron sputtering (DMS) for highly insulating layers, there is the choice between square wave pulse or sine wave power supplies.

How does a square wave generator work?

In DMS, the current path is perpendicular to the anode (right magnetron), through which the plasma is pushed towards the substrate. Sometimes it is argued that a square wave generator is the best choice for reactive sputtering, as it will deliver voltage, current and power at approximately 100% duty cycle during each half-wave.

Does a square-wave inverter work?

So, depending on the specifics of the appliance, powering them from a "square-wave inverter" might work ok, might not, or might even damage it permanently, it all depends on the specifics of the appliance.

Which power supply is best for a low power rating?

For illustration, the CAPEX for a power supply is shown as a function of the rated output power in Figure 9. For low power ratings up to 50kW, bipolar square generators are usually the better alternative. Here the flexibility regarding simple frequency changing and signal shape is useful.

Are bipolar square wave generators more flexible than sine waves?

Even at an early time it has been argued that a bipolar square wave generator is more flexible with respect to symmetry and duty cycle, but that sine wave generators are easier to implement for high output powers.

Do low power switch-mode power supplies really play up?

Even low power switch-mode power supplies that in one respect would be more impervious to this kind of treatment, actually aren't, and will in fact deliver poorer (noisier) DC to their electronic circuits, hence gadgets "play up".
