Funtions

The Universal Power Supply should provide these functions:

  • Inverter
  • Solid state transformer - 1200V, short range transmission lines - $60 cost of 45 kW transformer. [1]
  • 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
