timing switching to reduce startup surge
Exactly when an inductive load is switched on effects the peak current drawn over the next half cycle. Perhaps non-intuitively, switching an inductive device on while the AC waveform is at a voltage peak significantly reduces the peak current flow. Has anyone looked at using this to reduce startup surge for a motor? For example, a pressure switch on a well pump might be connected to a "peak switcher" box and then to the pump.
