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.
