Hi, well they look like boost buck xmfrs, and the second looks like 1/3 of a
say 440 to 220vac type xmfr, simular to the 3 phase ones with 3 coils. the
other possibility is a ballast type xmfr. i use a light bulb in series with
120 volts to find the ratio or sometimes a low voltage xmfr like 12 volts.
