Since somebody was cool enough to actually ask this question in the comments on my YouTube video, I figured I'd take the time to explain how to make a boost converter. For a better discussion by someone who actually has an EE degree, I highly recommend looking at ladyada's page, here. It is awesome and she's awesome. The project listed there is a little different, and the boost converter is built in a different way from mine, but it's essentially the same idea.

Problem with Boost Converter Circuit Problem with Boost Converter Circuit Thank you all for your responses so far. As it turns out, the 100ms of undefined PWM output was killing the boost converter. I replaced the IGBTs with MOSFETS (IRFP450B) and placed 4.7kΩ resistors pulling the gate down to ground. (Thanks Tahmid)However, I've run into another problem related to the ADC of the PIC microcontroller. In the circuit, I use a voltage divider of 10kΩ and 1MΩ to step down the voltage going into the analog input by a factor of approximately 100. Based on the pseudo-code provided below, after I push the start button, the circuit should charge the capacitor bank to 200V and then stop (it does not actively maintain 200V).
DC-DC HV Boost Converter How Does A Boost Converter Work? Basic Principal: A boost converter works in two stages, ON and OFF. In the ON stage the Semi-conductive Switch is conducting and current builds up in the inductor producing an electromagnetic field, this field stores energy. DC-DC HV Boost Converter
