Detailed data
GE IS200DSFCG1AEB Driver Shunt Feedback Card
The IS200DSFC 1000/1800 A IGBT Gate Driver/Shunt Feedback Board (DSFC) contains current sensing circuitry, fault detection circuitry, and two IGBT gate drive circuits. The driver and feedback circuits are electrically and optically isolated.
The board is designed for the innovative family of 1000 A and 1800 A pulse width modulated (PWM) source bridges and AC drivers. The DSFC board interfaces with the drive control via the IS200BPIB Drive Bridge Personality Interface Board (BPIB). A 1000A source bridge or driver requires three DSFC boards, one per phase. An 1800A source bridge or driver requires six DSFC boards, two "series" DSFC boards per phase.
The DSFC (G1) is designed for drive/source applications with an AC input of 600VLLrms. The DSFC boards mount directly to the upper and lower IGBT modules in each phase leg to keep the drive output and shunt input connections as short as possible. The circuit board is fixed by connecting to the gate, emitter and collector of the IGBT. In order to locate the gate, emitter and collector mounting holes, the circuit board must be properly positioned.
The DSFC board contains the plug and piercing connectors, mounting hole connectors (to connect to the IGBTs), and LED indicators as part of the board. There are no configurable hardware items or fuses as part of the board. The DC link voltage and output phase voltage sense wires are connected to the piercing terminals. All connections to the IGBTs are made through the mounting holes on the DSFC board through the mounting hardware.
Power Supply
The high voltage side of each driver/monitor circuit is powered by an isolation transformer.
The primary of this transformer is connected to a ±17.7 V peak (35.4 V peak-to-peak), 25 kHz square wave. Two of the three secondaries are half-wave rectified and filtered to provide the isolated +15V (VCC) and -15V (VEE) (unregulated, ±5%*, 1A average maximum for each voltage) required by the upper and lower IGBT driver circuits.
The DSFC board contains header and piercing connectors, mounting hole connectors (for connecting to the IGBTs), and LED indicators. There are no configurable hardware items or fuses on the board. The DC link voltage and output phase voltage sense wires connect to the piercing terminals. All connections to the IGBTs are made through mounting hardware through mounting holes on the DSFC board.
The third secondary is full-wave rectified and filtered to provide the ±12 V isolation voltage required for the shunt current feedback voltage-controlled oscillator and fault detection circuits (unregulated, ±10%, 100 mA average maximum for each). The shunt circuit also requires a 5 V logic supply (±10%, 100 mA average maximum), generated by a 5 V linear regulator connected to the +12 V supply. Only the 5 V supply is regulated.
Maximum loads are as follows:
±17.7V 0.65A rms
+5V 150mA
Frequently asked questions about the product are as follows:
-What is the GE IS200DSFCG1AEB Drive Shunt Feedback Card?
-The IS200DSFCG1AEB is a drive shunt feedback card used in Speedtronic turbine control systems. It is designed to manage feedback from the exciter (or generator), controlling the power to the turbine rotor. This feedback is essential to maintaining the correct speed and performance of the turbine by adjusting the output of the exciter based on the actual performance of the rotor.
-What are the main functions of the IS200DSFCG1AEB?
It processes signals from the turbine exciter or generator to ensure that the correct feedback is provided to the control system. The card helps manage voltage regulation by providing feedback from the exciter shunt circuit to keep the electrical output of the turbine within a safe range. The IS200DSFCG1AEB conditions the signals to ensure that they are suitable for use by the turbine control system. It is also responsible for monitoring the exciter and generator for faults or out-of-range values, providing protection for the turbine's electrical system. The card communicates with the rest of the turbine control system, ensuring proper coordination between turbine speed, load, and electrical output.
-What are the main components of the IS200DSFCG1AEB?
The microcontroller/processor processes the feedback signals.
The signal conditioning circuit filters and conditions the incoming feedback signals to the turbine controller.
The connectors and terminals are used to interface with the exciter and other components in the turbine electrical system.
The indicator lights are used for status monitoring, error reporting, and diagnostics.
The input/output (I/O) ports are used to communicate with other control modules in the turbine control system.
