GE IS200ERDDH1A IGBT Exciter Regulator Interface and Dynamic Discharge Board

GE IS200ERDDH1A IGBT Exciter Regulator Interface and Dynamic Discharge Board

Functional Description

The IS200ERDDH1A is an IGBT Exciter Regulator Interface and Dynamic Discharge Board used in the EX2100

regulator control (simplex and redundant) applications. For simplex applications, one ERDD is mounted in

the ERBP and interfaces with the ERIO and the Exciter Regulator Static Converter board (ERSC). In redundant

applications, one ERDD is mounted in ERBP (M1) and a second ERDD is mounted in ERRB (M2/C) and

interfaces with the ERIO, ERSC, and the Exciter Regulator Redundant Relay board (ERRR).

Features

• Gate drive control for field excitation

• Dynamic discharge to control excessive dc link voltage 

• Bridge feedback to monitor dc link voltage, output shunt current, output field voltage, bridge temperature,

and IGBT gate drive status (power supplies and desaturation conditions) 

• Control of the charging relay (K3) in all applications and control of the bridge output contactor (K41) in

simplex applications
