Physical Characteristics and Installation
This GTO gate driver board weighs approximately 0.72 kg for secure rack mounting. Its dimensions measure 280 mm x 80 mm x 25 mm for Mark V drive racks. First, align the DS200GGDAG1A DS200GGDAG1AHE with the backplane connectors. Then, press firmly until the board seats completely. Finally, secure the board using the top and bottom retaining screws. A conformal coating protects the PCB from moisture and dust.
Gate Drive Specifications
The DS200GGDAG1A DS200GGDAG1AHE provides 3 independent gate driver channels for GTO thyristors. Each driver outputs +15V for turn-on and -10V for reliable turn-off. The peak gate current reaches 15 A for fast switching of large GTOs. You can configure the switching frequency between 1 kHz and 5 kHz. Desaturation detection on every channel protects against short-circuit conditions.
Protection Features and Component Layout
This GTO driver board includes desaturation detection for each power device. The circuit monitors GTO anode-cathode voltage during conduction. A fault signal immediately disables the gate driver upon detection. 4000V RMS isolation separates the low-voltage control circuits from the high-power GTOs. The board contains 18 integrated circuits for gate drive and protection logic. Thirty-five capacitors provide filtering and bootstrap charging. Forty resistors establish proper timing and current limits. The “AHE” suffix indicates a revised PCB layout or newer component revision.
