- Induction furnace
- Plasma cutter
- Welder
- Laser cutter
- Charge controller to batteries
- Power conditioning from a windmill
- Induction heater
- Contactor
- Electric motor speed contoller
- Stepper motor controller
Part Reduction
What is the minimum number of electronic parts required to build the Universal Power Supply?
- Arduino for control. Arduino can also measure frequency to 50kHz for feedback - [2]
- IGBTs - choose one that can be scaled extensively, 10kW range (20A x5, 100V)
- Resistors
- Capacitors (filters)
- Small transformers
- Current sensors - Hall Effect Sensors
- Terminal blocks, 50A [3]
- Wire (8 ga, 55A, 600V) [4]
- Switches. Small switches, with IGBT serving as larger switch or contactor
- 200A contactor relay - 48DC - [5]
- Go for 600V on components, at 50A for wires, need 7 wires for 210kW - manageable as a modular system
