6 FAQs about Igbt voltage level 1500v inverter

Can 1700 V IGBT power modules be used for 1500 V DC?

Using 1700 V IGBT power modules for 1500 V DC applications carries many risks for unpredicted converter failures. Instead, a newly developed 2.0 kV Class IGBT module is enabling a reliable and efficient usage of simple 2-level topology for 1500V DC renewable inverter systems.

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 .

Can LV100 IGBT modules be paralleled?

Image used courtesy of Bodo's Power Systems [PDF] The LV100 IGBT module housing concept is designed for parallel operation. In this evaluation, a paralleling of three modules has been considered with an achieved output power of 1800 kW. This result in a power of 600 kW per module.

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.

What kV class IGBT is required for a 2 level topology inverter?

Due to the limitation of 1700 V class IGBTs under such operating conditions, a new 2.0 kV class IGBT is required to enable a reliable operation of a 2-level topology inverter at the required DC-link voltages.
