        More Information

        Overview Manuals Gate Drive Fiber Status Power Rails Board Service

        Features:

        • Two gate-driver channels on one board supply the A and B paths for a single SCR-bridge phase.
        • Each gate driver can energize the isolation-current-transformer chain for one to six series-connected SCRs.
        • Fourteen optical receivers and one optical transmitter separate firing commands from cell and supply status.
        The gate pedestal supplies the initial 20 to 25 A peak, after which the backporch stage maintains 5 A rms at the FGPA output for the remainder of the command.

        U101 and U201 receive the two gate commands, U301-U312 collect the FHVA cell indications, and U318 returns the multiplexed status word to the control.

        P5, P40, and P90 are supervised by the undervoltage logic; P15 is available as a separate auxiliary level but is not monitored.

        The General Electric DS200FGPAG1A Gate Pulse Amplifier Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Matching the port to the external device

        • Gate A command: U101 / AGATEIN receives the channel-A optical firing command
        • Gate B command: U201 / BGATEIN receives the channel-B optical firing command
        • Gate A output: E101 AGATE1 and E102 AGATE2 feed the FHVA transformer loop; E103 is AGND
        • Gate B output: E201 BGATE1 and E202 BGATE2 feed the second loop; E203 is BGND

        Matching the port to the external device

        • Cell inputs: U301-U312 receive blocking-state light from as many as twelve FHVA channels
        • Return link: U318 transmits twelve SCR status bits plus switching-supply status
        • State meaning: Received light indicates that the monitored SCR is blocking voltage
        • Cable arrangement: U101/U201 are designed for a duplex command cable; cell-status connectors are simplex

        Matching the port to the external device

        • P5: 4.7-5.1 V dc logic supply
        • P40: 25 V dc gate-backporch supply point
        • P90: 81 V dc gate-pedestal supply point
        • P15: Typically 13.5-14.5 V dc and not included in undervoltage monitoring

        Matching the port to the external device

        • Service scope: The board has no fuses or other end-user-serviceable parts
        • Power isolation: Turn power off and verify that no voltage remains before touching the board
        • Handling: Use a grounding strap and store the board in an antistatic bag or box
        • Identification: Record the full part number, equipment order data, LCI model, and board description
        Description
        General Electric DS200FGPAG1A is a Gate Pulse Amplifier Board serving one phase of an LCI SCR bridge. Two gate-driver circuits translate optical firing commands into isolated gate power for the series-connected SCRs.

        Within DS200FGPAG1A, a charged pedestal pulse starts conduction and the regulated backporch current maintains the gate command for its remaining duration. The gate current travels through the isolation transformers mounted on the associated FHVA boards.

        Cell-blocking indications from the FHVA boards are multiplexed by DS200FGPAG1A and returned to the control over a serial optical link together with its power-supply status. The on-board switching supply provides the control voltages used by both gating and status functions.

        Technical notes
        The P15 auxiliary supply on DS200FGPAG1A is not included in the board’s undervoltage monitoring. Measure it separately when the monitored P5, P40, and P90 rails appear normal but gate or status behavior remains abnormal.

        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.
        VIEW ALL FAQS
        Why can DS200FGPAG1A receive a gate command but produce no SCR gate current?
        On DS200FGPAG1A, the U101 or U201 command receiver and the matching AGATE or BGATE power output are separate stages; verify supply and trace both stages.
        When only some series-connected SCRs fail to turn on, how should DS200FGPAG1A be checked?
        Each DS200FGPAG1A driver can feed one to six FHVA isolation transformers in series, so inspect the complete conductor loop and every series connection.
        If DS200FGPAG1A still gates normally, why can SCR cell status disappear?
        The DS200FGPAG1A command and return fibers are separate; loss at U301–U312 or U318 can remove status without stopping gate commands.
        What should be measured when DS200FGPAG1A reports a supply undervoltage?
        Measure the monitored P5, P40, and P90 rails on DS200FGPAG1A, then check P15 separately because that auxiliary rail is not monitored.
        How can crossed fibers be prevented during a DS200FGPAG1A replacement?
        Keep the DS200FGPAG1A command pair at U101 and U201, return each status fiber to U301–U312, and reserve U318 for outgoing status.
        Before DS200FGPAG1A is removed, which handling mistake must be avoided?
        Power must be verified absent before DS200FGPAG1A removal, and optical connectors should be released by their bodies rather than pulled by the fibers.
        Which records reduce the risk of ordering the wrong DS200FGPAG1A?
        Match DS200FGPAG1A by its complete stamped number, LCI identity, bridge phase, fiber assignments, and gate-stab connections rather than by board appearance.
