Electric OU: AC Component Across the CVR During Oscillations
i took 2 LEDs and mounted them back-to-back, anode of one to cathode of the other and vice versa. I put these LEDs in parallel with the Tar Baby’s 0.25 Ohm current viewing resistor (aka shunt, CVR). Using the standard negative-going pulse to produce the oscillations, the LEDs show enough AC across the CVR to light up both LEDs, but the amp meter in series with the battery shows about 60 mA. When I use a bipolar pulse to drive the gates, I get strong heating of the load since the Q1 mosfet is on during the NON_oscillation portion of the waveform, and the DC current drawn is something around 1.5 amps. And the LEDs are of course still lit.
