More Information

Overview Manuals SCR Gate Paths Converter Feedback Dynamic Braking Connector Map

Features:

  • Interfaces a six-pulse firing source with three discrete bridge SCRs.
  • Encodes DC-link shunt feedback on a frequency signal for control processing.
  • Returns dynamic-braking and converter-temperature conditions when fitted.
SCNV consolidates the low-level bridge signals that cross between Innovation Series control electronics and a standalone power converter.

Its feedback circuits represent measured converter conditions separately from the gate-pulse transformers that deliver firing commands.

Because setup components are absent, board selection depends on matching the bridge current class and the non-paralleled SCR topology.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Six-Pulse Firing Interface

  • Device count: One board drives three bridge SCR devices.
  • Size boundary: Supported discrete SCRs are no larger than 66 mm.
  • Pulse coupling: Gate commands cross the power boundary through transformers.
  • Topology limit: The interface does not serve paralleled SCR arrangements.

Measured Bridge Signals

  • DC-link sensing: A shunt input represents converter bus voltage.
  • Frequency encoding: The VCO sends the measurement across a 0-2 MHz range.
  • Phase information: Connector paths return bridge phase conditions to control.
  • Current channels: Converter-current feedback remains separate from gate outputs.

Optional Brake Interface

  • Gate command: An onboard path can drive the braking IGBT.
  • Desaturation return: The interface reports an IGBT desaturation condition.
  • Supply supervision: Undervoltage feedback identifies a gate-driver supply problem.
  • Thermal state: A thermostat circuit carries converter-temperature status.

External Signal Boundaries

  • Backplane: P1 provides the 128-pin connection to control electronics.
  • Cable interfaces: Six plug connectors route bridge and braking signals.
  • Test access: TP1-TP4 are reserved for engineering measurements.
  • User controls: No LEDs, fuses, jumpers, or adjustable points are provided.
Description
Designed for the GE Innovation Series, General Electric IS200SCNVG1A is the converter interface board between control electronics and a standalone SCR-diode bridge. It supports the 1000 A and 1800 A converter arrangements that use a six-pulse firing source.

Gate commands handled by IS200SCNVG1A drive three SCRs, each no larger than 66 mm, through pulse-transformer interfaces. The board is not the interface for bridges built with parallel SCR devices, which establishes a clear converter-hardware boundary.

A shunt-voltage channel on IS200SCNVG1A converts DC-link feedback into a 0-2 MHz voltage-controlled-oscillator signal for transmission to the controller. Additional connector paths carry bridge phase and current information between the power structure and control section.

Where the converter includes dynamic braking, IS200SCNVG1A provides the IGBT gate-driver path together with desaturation and undervoltage fault returns. A thermostat circuit also reports converter temperature state through the interface.

Six plug connectors and the 128-pin P1 backplane connector form the external interfaces of IS200SCNVG1A. There are no user LEDs, fuses, or adjustable hardware; TP1-TP4 are engineering test points in circuitry that can carry 575 V AC or 900 V DC.

Technical notes
General Electric IS200SCNVG1A connects six-pulse SCR gate paths, converter feedback, and optional dynamic-braking signals in Innovation Series standalone converters.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Will IS200SCNVG1A work with a bridge that parallels multiple SCRs per phase?
No. IS200SCNVG1A is defined for three discrete SCRs up to 66 mm and not for converter legs using paralleled SCR devices.
There are no status LEDs on IS200SCNVG1A. How is board condition evaluated?
IS200SCNVG1A returns bridge, braking, and temperature states through its control interfaces; it contains no user LED diagnostics.
Which signal should be traced when IS200SCNVG1A reports an incorrect DC-link value?
Trace the shunt input and the 0-2 MHz VCO feedback path on IS200SCNVG1A before investigating the separate phase or current channels.
What IS200SCNVG1A feedback distinguishes a braking-device fault from a low driver supply?
IS200SCNVG1A provides separate dynamic-braking returns for IGBT desaturation and gate-driver undervoltage.
Can TP1-TP4 on IS200SCNVG1A be used as routine field adjustment points?
No. IS200SCNVG1A has no user adjustments; TP1-TP4 are engineering test points in circuitry that may carry hazardous converter voltage.
Which converter assemblies define the installation boundary for IS200SCNVG1A?
IS200SCNVG1A belongs to 1000 A and 1800 A standalone Innovation Series SCR-diode converter arrangements using six-pulse firing.
