Power Semiconductors, Diamond Films, Capacitors

Diamond Films for Power Semiconductors, Capacitors and Thermal Packages

• Thermodynamic analysis of an active denial pulsed power system for optimization of size and performance
• Scaled from a ground based demonstrator to a C-130 cargo aircraft based power system

1. A 5 kW, 2.45 MHz Microwave Reactor
2. Microstructures of diamond films without a "novel" nucleation process (larger grains) and with a "novel" nucleation process (finer grains)

Control Electronics for a Portable Generator

1. Control board integrated with the generator
2. Circuit board layout

• Developed and delivered control electronics board for the 360 W portable generator.
• Control board includes the following components:
  • Drive terminals
  • Generator output terminals
  • Brake resistors
  • Battery terminnals
  • DC voltage for externally charging the battery
  • Switch terminals for starting up the generator unit
  • Battery-state indicator switch
  • Speed signal
