i need a place where i can show some of the interesting scope-shots that we can get when working with poc-coils.
take a look at this one...
CH1: voltage from primary coil (series tank circuit)
CH2: current from primary coil
CH3: POC under load (resistive and inductive load in parallel)
CH4: Source dipole (input voltage)
when you look at the voltage from source you can see when the switching happens (on/off). the output on poc is pumped up by the circulating current. even when the switch is off, we can see the energy generation on the poc coil.
a second one taken at higher frequency..
instead of poc output we see the power which is circulating inside the tank-circuit and the power which is consumed.
have a nice day!
