【英文介绍】
ABB 5SHX1445H0002 3BHL000387P0101 DC speed regulating medium pressure board
IGBT series high frequency driver board mainly adopts SG3525A as PWM pulse formation, the output pulse frequency range is 20Khz-60khz, the pulse interval is 180 degrees each other, the dead time can be adjusted. It can be applied to frequency and power regulation of IGBT full-bridge inverter series resonant induction heating device. Power range: 10kwe-120kW, the control board less wiring, centralized control, no debugging, the working power supply voltage for three AC double 18V/1A and four 22V/0.5A power supply. With over current, over voltage, but water, a variety of state indicators, and to provide switching type Hall protection interface and linear hall protection interface, a full bridge inverter IGBT drive circuit, this board can be directly assembled IGBT high frequency induction heating device.
IGCT integrates the GTO chip with the anti-parallel diode and gate driver 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.
The performance of thyristor is displayed in the on-stage, and the characteristics of transistor are displayed in the off-stage. IGCT has the characteristics of large current, high blocking voltage, high switching frequency, high reliability, compact structure, low on-off loss and so on, and has a good application prospect.
IGCT has been used in power system power grid devices (100MVA) and medium power industrial drive devices (5MW)IGCT has been successfully applied in the field of medium voltage inverter for 11 years (until 2009), because the high-speed switching capability of IGCT does not need buffer circuits, so the number of power components required is less.
The reliability of operation is greatly increased. The IGCT combines the high-speed switching characteristics of the IGBT (insulated gate bipolar transistor) with the high blocking voltage and low on-loss characteristics of the GTO (gate shutdown gate tube), and the trigger signal is generally transmitted to the IGCT unit through the optical fiber.
In the phase module of the ACS6000 marginal rectifier unit, each phase module consists of an IGCT, a diode, and a clamp capacitor, and is powered by an independent gate power supply unit GUSP.
