5SHX1445H0002 ABB thyristor. Thyristor (Thyristor), also known as thyristor rectifier, was once referred to as thyristor, in 1957 the United States General Electric Company developed the world’s first thyristor products, and commercialized it in 1958.
The 5SHX1445H0002 ABB thyristor is a new type of power semiconductor switching device (integrated gate converter thyristor = gate converter transistor + gate unit) developed by medium voltage frequency converter for use in large power electronics sets. It was proposed by ABB in 1997. IGCT has made great progress in power, reliability, switching speed, efficiency, cost, weight and volume, and has brought a new leap to power electronic complete sets.
5SHX1445H0002 ABB thyristor 1GCT 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 switching force of the transistor and the advantages of the low on-state loss of the thyristor to give full play to the performance of the thyristor in the on-stage. The off phase presents the characteristics of the transistor. GCT has the characteristics of high current, high turn-off frequency, high reliability, compact structure, low on-off loss, and low cost, high yield, so it has a good application prospect. Has been used in power systems for power grid devices (100MVA) and medium power industrial drives (5MW)1GCT in the field of medium voltage inverter successful application for 11 years (up to 2009), 5SHX1445H0002 ABB thyristor due to IGCT high speed switching capability without buffer circuit, Therefore, the number of power components required is less, and the reliability of operation is greatly increased
