Functional Description

IS200PICHG1A is an Phase Interface Control Board developed by GE. It is a part of the Drive Control control system. The Phase Interface Control board consists of three sub-assembly boards- the Temperature Feedback Board, VCO Feedback Transmitter board, and IGBT Gate Driver Board.

Overvoltage Trip Signals

• It generates several overvoltage trip signals. One such signal acts as a logical overvoltage comparator, monitoring each half of the available DC buses.
• Additionally, it controls undervoltage signals through a PICH board. The model includes a hardware jumper to reduce the overvoltage trip point.

Sub-Assembly Boards

• TFBH (IGBT Temperature Feedback Board): Provides two thermistor temperature feedback channels for monitoring IGBT cold-plate temperatures.
• VCXH (Feedback Transmitter Boards): Four boards monitor DC capacitor bus voltages, phase currents, and phase-to-neutral voltages. One board monitors phase currents, one phase-to-neutral voltages, and the remaining two monitor DC capacitor bus voltages.
• IGDH (IGBT Gate Driver Boards): Eight boards provide the necessary circuitry to interface an IGBT module to control logic.

Features and Components

• Integrates feedback signal processing circuits and gating drivers for four dual IGBT modules of the H-bridge phase assembly.
• Includes thirteen daughter boards (eight IGBT Driver Boards, four VCO Feedback Transmitter Boards, and one IGBT Temp Feedback Board) soldered onto the primary board.
• Equipped with LEDs, a jumper switch, test points, plug connectors, stab-on connectors, and fiber optic connectors.
• Incorporates high-voltage capacitors, heat sinks, inductor coils, and transformers.

Logic Ground Planes

• Features two logic area ground planes: power ground (SHCOM) and signal ground (DCOM). Logic circuits supplied by +5V are referenced to the signal ground.
