3-to-180V Boost Converter

[Ignore the digital stuff at the top half of circuit as its just there for various monitoring & testing purposes] The circuit in the bottom left quadrant of the schematic is the main circuit for the converter. It’s a self starting RLC oscillator that was meant to run around 2kHz but seems to sit around 2.2kHz. It requires a 3VDC source only and switches this into the RLC circuit at its resonance to slowly build to a point where it can run the 180VDC load at the bottom right part of the circuit. The bottom-middle is just a bridge rectifier for the high voltage AC from the RLC to DC. I haven’t yet tested this circuit for real, was just done in EC out of curiosity.
