Technical description: ABB 5SHY3545L0014 DC speed regulating medium pressure plate semiconductor

IGCT integrates the GTO chip with the anti-parallel diode and gate drive circuit, and then connects it with the gate driver in a low inductance mode at the periphery, combining the stable turn-off ability of the transistor and the advantages of the low on-state loss of the thyristor, giving full play to the performance of the most intertube in the on-stage, and showing the performance of the transistor in the off-stage. ICT has the characteristics of large current, high blocking voltage, high switching prerate, high reliability, compact structure, low on-off loss, etc., and causes low cost and high yield, so it has a good application prospect. It has been used in power system power grid device (100MVA) and medium power industrial drive device (5MW)GCT in the field of medium voltage inverter has been successfully applied for 11 years (until 2009), because the high-speed switching capability of IGCT does not need slow circuit, so the number of power components required is less and the reliability of operation is greatly increased. The IGCT integrates the high blocking voltage and low on-loss characteristics of the IGBT(the high-speed switching characteristics of the insulated gate bipolar transistor and the GTO gate turn-off intertube), and generally transmits the signal to the GCT unit through the optical fiber. In the phase module of the ACS5000's marginal rectifier unit, each phase module consists of an IGCT and a diode, a clamp capacitor, and is powered by an independent "] pole power supply unit GUSP.
