According to TriField EM100 line EMI meter, switched-mode power supplies for power amplifier, my monitor, and my computer collectively decrease dirty electricity between 10khz and 10mhz on hot wire by 10 millivolts.
Michael Schwabe said capacitive filters such as greenwave filters and stetzer filters decrease dirty electricity on hot wire by utilizing large capacitors. But, according to his test results, those capacitive filters increased dirty electricity below 10khz on hot wire and magnetic field above 1khz on neutral wire. Capacitive filters also increased dirty electricity on neutral wire.
If switched-mode power supplies act like capacitive filters, I would suspect they increase dirty electricity below 10khz on hot wire, magnetic field above 1khz on neutral wire, and dirty electricity on neutral wire.
Do they seem to decrease dirty electricity on hot wire because they use capacitors?
Or, do switched-mode power supplies have components that reduce dirty electricity?
