I need help switching an active inductor controller using inductive reactance to control the current of two feeds. The circuit I have built uses make-before-break switching just like a rotating brush making contact with two contacts at a time for non-sparking and continuous current flow. Below is the main device and circuit.
What I need is a switching circuit that can change the positions of a contact, just like the brush rotation or movement. When started, the voltage will be 100 V but will climb to 140 to 160 V suppressing the starting voltage. In the picture above, I want the brush to be replaced with a high-side switching circuit. I know it can be done but how?
The switching circuit I have now is a Teensy 4.0 on a custom 8-chip shift register board that works very well. I just need to marry it to a transistor board to switch the active inductor controller. This will change the inductive reactance and thus the current flow of two separate feeds 180° from each other.
Yes I will be replacing the moving brush with 60 taps across the top of the active inductor controller. This is just like an AC variac except there is no sine wave just DC, so I have to continuously move the contact to achieve on going inductive reactance according to Farday in 1831. What this does by changing the amount of windings on either side of the brush, I am actually changing the inductance which is the opposition to current flow which gives the DC, AC-like qualities thus controlling the current flow with inductive reactance of both feeds 180 degrees out ie... one increasing , one decreasing.
The high-side driver and transistor switches will be connected to and switched using a Teensy and a custom shift register board I designed myself. It is on this YouTube video.
So with this connected to the high-side driver switching at the 60 taps on the controller, I can achieve my goal of replacing a rotating brush with electronic switching. Please keep in mind the Teensy is 3.3 volts but the shift registers are at 5 volts, so the high side driver transistor has to be able to be switched with 5 volts yet handle voltages around 100 starting volts to a running voltage of upwards of 160 volts.
I hope this clarifies things a little, but if it does not I can give further information.
