Hi All,
Question: I built a replica of JB's lab SG with 21 magnets and fan blade for governor. 7 leads with 1 trigger.
Prior to modifying the schematic I could run this system with anything from 6 volts to 30 volts and all the happened is that the output increased as the voltage was increased while the input current rose slightly from 1 amp to 3.5 amp.
I modified this schematic by the addition of the three diodes like the "dvd 33" forced charge and things have greatly changed. One diode is on the input positive, one is on the input negative and one is on the output going to the charge battery. It still works great but the tuning is very touchy and the voltage range at which it will run is a very narrow window.
Any voltage beyond 13 volts and the system dies off. Does anyone know what is happening here? Not that it really effects the charging ability but the tuning has a very narrow band. Is this an impedance issue on the primary side?
I am using a Lambda variable power supply on the front end.
