250W 2kV Power Supply

I've identified a control loop instability that prevents the PFC output voltage from settling correctly. Once I have the instability corrected, it shouldn't take long to finalize the board layout and assemble a prototype.

The board layout is about 60% complete. Waiting on final SPICE analysis before completing the remaining regions.

The SPICE analysis and final circuit design are almost complete. Currently working on the soft-start circuitry, power-on stability, and verifying that no components are over stressed. After that I just need to verify the output capacity and stability over the input voltage range, check that the input power factor is acceptable, and ensure that the EMI filtering fully blocks the switching noise.
