What if 1700V class IGBT is used in 1500V solar inverter system?
For example, when 1700V class IGBT is being used in 1500V solar inverter system in 2-level or NPC2 topology, at a VCE utilization ratio over 88% the failure rate will be unacceptably high despite short exposure to such input voltage.
What is the maximum IGBT voltage?
With maximum voltage of 1500V across DC link, at the first glance it is tempting to consider using 1700V class devices in 2-level or NPC2 topologies, for maximum utilization of IGBT voltage rating for maximum possible output power at lowest cost. However, the factor of cosmic radiation induced IGBT failure must be considered .
What is a 1500V solar inverter?
1500V solar inverter at megawatts level in NPC1 topology enabled by high-density IGBT module Centralized solar inverter applications in MW-class require high current rated modules or a high amount of paralleled modules.
Which IGBT topology is best for a VDC inverter?
An optimized intermediate voltage class IGBT blocking capability is commercially not available to support VDC applications. As a result, a 3-level topology based on V IGBTs is the preferred topology nowadays for inverters with DC-link voltages of up to VDC in the field of renewable energy applications.
How to achieve low inductive commutation in 3 level central PV inverters?
High power 3-level central PV inverters with low inductive commutation can be realized by using half bridge IGBT modules. It has been shown that by using LV100 IGBT modules in combination with the active neutral clamp (A-NPC) topology, a low inductive commutation path is available for all operating modes.
Which circuit topology is best for a volt inverter?
As a result, a 3-level topology based on V IGBTs is the preferred topology nowadays for inverters with DC-link voltages of up to VDC in the field of renewable energy applications. A half bridge circuit configuration is the prevalent circuit topology of high power V IGBT modules.
