This week progress was limited due to waiting on component delivery – the LCR meter needed for precise tuning and testing hasn’t arrived yet due to repeated Amazon delivery failures. I used the time to refine the interrupter circuit design and verify my previous duty cycle fix is still holding stable across the full frequency range. I also assisted Caleb with diagnosing the gate driver failure and confirmed the interrupter output wasn’t the cause – the issue was no output load causing power to dissipate in the chip. Next week once the LCR meter arrives, I’ll work with the team to tune the primary-secondary coil coupling and verify the complete audio modulation chain functions properly.
