Hi Doug Ole guys, In the BITT circuit I was wondering is most of the losses only occur at low power levels.
 As I have never gotten OU out of it even though Lenz effect seems to go away.
 

 So I made up a simple (although not terrific) version out of some Microwave Oven Transformer (MOT) cores and coils.
 Tested at low signal inputs and also high 240V ac levels from car battery and inverter.
 My best results at 240Vac gave 2.91 Watts out for 2.78 Watts in.
 

 Other more typical & less than OU results are shown on the attached pics.
 The slightest error in the phase measurement makes a huge difference to the efficiency results.
 

 The primary for BIIT input I used was the High Voltage winding.
 The secondaries were two primary coils off MOT

 will send 2nd email with other 2
