Continuing the current waveform and power factor discussion, I captured a few current waveforms. I think their potential to confuse a voltage regulator speaks for itself. I wish I could capture the pictures using a Chinese generator, but I just don't have one.
This is an incandescent light bulb. Current is on the top, voltage on the bottom.
This is a compact fluorescent. I'm not surprised that the Kill-a-Watt doesn't care for it.
A conventional transformer-rectifier power supply.
A Eureka Mighty Mite vacuum cleaner. Note the noise in the waveform.
PD9160A converter with no load. Noise visible here, too.
PD9160A with 7 amp load.
Finally, PD9160A with 65 amp load. There's still noise on the waveform. It looks smaller because the trace is scaled down to fit the higher current reading.
