Saturation characteristics of electrostatic spray gun transformer

The transformer (16) in the power supply (14) of an electrostatic spray gun (12) is designed to start saturating before the maximum desired output current is reached. During saturation, as the transformer secondary current goes up, the output voltage goes down, thus obtaining the desired output load...

Zusammenfassung:The transformer (16) in the power supply (14) of an electrostatic spray gun (12) is designed to start saturating before the maximum desired output current is reached. During saturation, as the transformer secondary current goes up, the output voltage goes down, thus obtaining the desired output load line with much less tip resistance. Since the transformer (16) was designed to saturate earlier, it was also smaller in size. This reduced overall size and weight of the gun (12) compared to prior art power supplies have larger transformers and tip resistors.
