FCOVF6100 Variable Frequency Firing Board

FCOVF6100 Variable Frequency Firing Board

The FCOVF6100 variable frequency firing board provides the functionality of the industry-standard FCOG6100 firing board for applications with variable-frequency AC mains. An onboard frequency compensation scheme makes the firing circuit less sensitive to line frequency variations while an isolated DC-DC converter provides enhanced control power flexibility. The FCOVF6100 is offered in a standard 30-140 Hz frequency of operation range and customer-specific ranges to 600Hz.

Key Features

  • Analog Delay Angle Command Signal (SIG HI) 0-5 V, 0-10 V, 4-20 mA, or custom ranges.
  • Phase Loss Inhibit
  • Instant Enable and Inhibit
  • Phase Sequence Insensitivity
  • High Current Picket Fence Gate Drive
  • Analog Delay Determinator Circuit
  • Flexible Control Power Options
  • Assembled in the USA
  • Variable Frequency (30 – 140 Hz standard, or customer specific up to 600Hz)

Applications

  • Generator Exciters
  • Battery Chargers
  • Wind Turbine Controllers
  • DC Drives

 

Technical Details

The FCOVF6100  includes the following features:

  • Frequency Insensitivity: A frequency-to-voltage converter acts in concert with the delay angle determinator circuit to reduce delay angle variance over the operating frequency range. This scheme limits delay angle variance to approximately 3 over a frequency range of 30 to 120 Hz.
  • Analog Delay Angle Command Signal (SIG HI): Users may choose a variety of DC control signal ranges including 0-5 V, 0-10 V, 4-20 mA, or custom ranges.
  • Soft-Start and Soft-Stop: Upon soft-start, SCR firing is enabled and the delay angle command ramps from the maximum value to the setpoint value determined by the SIG HI command signal. Upon soft-stop, the delay angle ramps from the setpoint value to the maximum value after which SCR firing is inhibited.
  • Phase Loss Inhibit: A phase loss circuit instantly inhibits SCR firing if a loss of one or more phases or gross phase imbalance is sensed on the AC line. Firing will soft-start when such a fault is cleared.
  • Instant Enable and Inhibit: A contact closure (relay, switch, transistor) instantly enables or inhibits SCR firing at the delay angle commanded by the SIG HI delay angle command signal.
  • Phase Sequence Insensitivity: SCR gating is unaffected by mains voltage phase sequence.
  • High Current Picket Fence Gate Drive: The transformer-isolated gate drive circuits provide a hard firing initial 15 V open circuit/1.8 A short circuit firing pulse followed by sustaining “back porch” pulses at 7 V open circuit/0.5 A short circuit. The gate pulse burst frequency is 384 times the mains voltage frequency.
  • Analog Delay Determinator Circuit: Enerpro’s gate delay determinator circuit is based on the Ainsworth three-phase PLL circuit and implemented with a proprietary ASIC. This circuit adjusts the gate delay firing angle in negative proportion to the SIG HI command. Gate drive phase balance is typically less than ±1°
  • Flexible Control Power Options: The FCOVF6100 board is typically configured to accept 24 or 48 VDC control power. In this configuration, an onboard 20 W DC-DC converter rated for 1600 V isolation (with a voltage limiting Zener preregulator ) creates the necessary 30 VDC and 15 VDC rail voltages on the firing board. The customer may alternatively supply 30 and 15 VDC rails directly.
  • Board Construction: All circuit boards are assembled at the Enerpro plant in Goleta, California and are manufactured by a UL-approved fabricator from 2.4 mm thick FR4 fire resistant fiberglass epoxy laminate. All boards are conformal coated (MIL-1-46058, Type UR).
