Solid-State Transformers

Key Features:

• Novel “Cascade H-Bridge” Design with a bypass contactor on each AC bridge input

  •  Wideband voltage Regulation
  • Low-cost power PCB production
  • Multi-use AC/DC conversion blocks

• Silicon carbide (SiC) MOSFETs

• Programmable AC input power factor

• Dry type/liquid-cooled design

• Modular design accommodates power ratings of 1-10 MW

Competitive Advantages:

• Small footprint (2.82m width x 1.25m depth x 2.54m height)

• Reduced input current

• Simplified PWM control and power factor correction

• Improved overvoltage protection

• Survivability in the event of a phase loss

• Streamlined integration of distributed energy resources

Applications:

• 380-Volt DC distribution for standard building loads

• 1,500-Volt DC distribution for high-power electric vehicle charging

• Efficient microgrid power distribution
