IS200EHPAG1ACB Exciter Gate Pulse Amplifier Board
The IS200EHPAG1ACB Gate Pulse Amplifier Board (EHPA) is used in 100 mm EX2100 Excitation Control. It takes the gate commands from the ESEL and controls the gate firing of up to six Silicon Controlled Rectifiers (SCRs) on the Power Bridge. It is also the interface for current conduction feedback, as well as bridge airflow, line filter airflow and blown fuse detection, and bridge temperature monitoring.
Some revisions of EHPA include support for EHFC, an optional daughterboard that allows start/stop control of the bridge cooling fan or redundant (lead/lag) bridge cooling fans. Refer to GEI-100548 for details of the EHFC interfaces and operation.
The EHPA functional model with the major I/O is shown in the following figure. A nominal 125 V dc power source from the EPDM supplies an on-board dc/dc converter, that provides power for SCR gating over the full range of input supply voltage. LEDs provide visual indication of the status of the EHPA power supply, input gate commands from ESEL, EHPA outputs to the SCRs, currents into the bridge, line filter, cooling fan rotation, bridge temperature, alarms, or fault conditions.
