High Frequency Transformers

"GATE GUARD" series

Gate Guard series Transformers are built from unique platforms and offer the following advantages:

  • High isolation with extreme efficiency and reliability
  • Corona-free operation to 30KV or more eliminates losses and potential latent failures from partial discharge
  • Expressly designed for robotic assembly; include thru-hole mounting
  • Speed to market with new devices by using pre-designed base platforms
    • Withstands the harshest environments
    • Ruggedized to withstand high vibration
    • High operational voltage; up to 20 KV, and higher
    • Operates at industrial temperatures; -25°C to150°C
    • Optimized for total system performance

Ideal Applications for Gate Guard series Transformers:

  • Alternate energy: wind, solar, fuel cell
  • Hybrid vehicles: auto, bus, truck
  • Industrial drives
  • Transportation: rail, naval

Real-life example of a "GATE GUARD" IGBT Gate Drive Transformer Application:

  • AC Locomotive: Traction and braking system
  • Bicron has produced more than 1/2 million Gate Drive Transformers for this application
  • ZERO field failures to date!
  • Partial discharge (corona) tested (2500 VAC min, 20000 VAC max)
  • The Bicron solution eliminated recurring field failures that cost over $100,000 annually to repair

"STANDARD" series High Frequency/High Voltage Transformers

Standard series Transformers are available for the following functions:

  • Pulse: Ensures that the inductance remains in the defined range and avoids saturation.
  • Switch Mode: Contains a PFC Choke, Diff Mode Choke, Output Choke, and Switching Transformer.
  • Flyback: The output voltage is a function of the current retention in the transformer.
  • Feed Forward: A voltage controlled version of the current controlled flyback transformer.
  • Inverter: Generates voltages in excess of 1 KV from a low voltage input.
  • Buck Boost: Increases (boosts) or decreases (bucks) the input voltage.
  • Isolation: Generates a gross voltage (15V-200V) while providing high isolation.
  • STIM: When isolation between a medical patient and high voltages is critical.

High frequency, higher power level chassis-mounted transformers, designed for higher output voltages:

  • Output voltages greater than 1KV, up to 30KV
