Very High Power IGCT PEBB technology

Abstract

In the field of power electronics the Power Electronics Building Block (PEBB) is a key functional component. With regard to the applications, it is of outmost importance that the PEBB technology used is compact, costeffective and reliable.The IGCT is at the forefront of technology in high power, medium-voltage applications. For further improvement in size and costs a new ANPC IGCT PEBB has been developed. The main new technologies to achieve higher powers are the new low-inductive gate-unit to maintain hardswitched operation up to more than 6000A, the increased SOA of the 91mm asymmetric IGCT (4 inch technology) and the antiparallel diode up to more than 6000A and the Active NPC technology, which allows an optimum and equal loss balancing in all power semiconductorsThe maximum inverter output power has been increased by 80% with a parallel increase in the power density and reduced costs per kVA.I.

Converter-fed synchronous machine for pumped hydro storage plants

“…An example for this solution is the recently commissioned world's largest voltage source hydro converter at the Grimsel 2 power plant in Switzerland [2]. This converter is based on a 3.3 kV LL Active NPC high power converter solution [3].…”

“…In applications, power semiconductor cost understood as the combination of basic sem efficiency benefits and costs for enabling failure mode with (discharge) plasma con on the efficiency benefits, the application c of high voltage semiconductors. The efficiency is defined by a thyristor-based makes the IGCT (Integrated Gate Commu the preferred choice [3]. In regards containment at high current levels and failure mode needed for redundancy, t presspack devices is instrumental.…”

Design considerations for a PEBB-based Marx-topology ILC klystron modulator

“…Figure 1 illustrates a PEBB. Referring to [2,3], the functionality of a PEBB as a building block is defined as power conversion including: -power supply for gate drivers & sensors, -stack or module assembly including gate drivers, -voltage, current and temperature sensors (including A/D conversion of sensor signals), -switching control including pulse generation for gate driver, -communication with control, and -primary protection. PEBBs are configured together to form a system.…”

Application of IGCT in High Power Rectifiers

“…Since then, the performance and electrical rating of IGCT has increased dramatically and today 4.5-, 5.5-, 6-, 6.5-, 10-kV IGCTs are available [7], [8]. IGCT-based converters are used in industrial medium-voltage drives (MVDs) as well as railway interties and other energy management systems [9], [10].…”

“…IGCT-based converters are used in industrial medium-voltage drives (MVDs) as well as railway interties and other energy management systems [9], [10]. The maximum current rating of IGCT is much higher than IGBT and reliable turn-off at 6.5kA versus 2.8kVdc has been reported in the previous literature [8]. This remarkable switching capability at high current in addition to many other reliable features already proven in many other medium-voltage applications, IGCT has been anticipated as one of optimal turnoff switching devices for high power rectifiers.…”
