Hello everyone,
I’m working on designing a series of power supplies for capacitor charging and laser driving. I plan to start with a simple unit and then move on to higher power levels. I’ll be sharing my experiences and questions under this post, so I’d really appreciate your criticism, advice, and views.
Here’s my roadmap:
- Design a power supply for capacitor charging and constant current DC laser tube driving.
The power supply should have a 220Vac input and a 4kVdc output, with all protection circuitry (arc sense, short circuit, open circuit, overload, thermal overload, etc.).
- Design a 3-phase 380Vac input, 10kW, 12kV output DC power supply for a gas laser drive.
I’m planning to use C2000 series microcontrollers for this purpose. My initial plan is to base my designs over LLC topology. I’m interested in using GaN transistors, but in order to simplify the overall design process, I’ll probably stick to MOSFET/IGBT switches.
I have a few questions:
- Which C2000 microcontroller should I start with?
- Would you recommend using GaN transistors or traditional MOSFET/IGBT switches?
- Are there any other topologies that you would suggest within this context?
- Should I design a separate PFC circuit or incorporate PFC into the design?
Thank you for your help!
Best regards,
Adnan
