Do high-voltage and high-power IGBT chips have a carrier storage effect?

or Member, IEEEAbstract—High-voltage and high-power IGBT chips have a noticeable carrier storage ffect, which is related to the load current. However, the research on the carrier storage effect of existing IGBT behavior models is insuficient. In this paper, An improved behavioral mode

What are IGBT power modules?

In the second half of the 1990s, development and commercialization of IGBT power modules for high voltage ratings as 2500 V and 3300 V has started. Originally, these HV-IGBTs were designed as GTO replacement for high-power and high-reliability applications like for example railway traction inverters .

What is a HV-IGBT power module?

Originally, these HV-IGBTs were designed as GTO replacement for high-power and high-reliability applications like for example railway traction inverters . Additionally, the use in many other high-power applications has followed. The device package, which has been used back then, already had the same outline like today’s HV-IGBT power modules.

What are insulated-gate bipolar transistors (IGBTs)?

The insulated-gate bipolar transistors (IGBTs) at the heart of the sub modules are fully controllable. This enables modular multilevel converters to absorb and generate reactive power independently from active power up to the converter rating. The output currents can be varied over the complete operating range in a smooth, linear way.

Do IGBT power modules need a short circuit withstand capability?

To increase converter robustness and decrease downtime after a failure, IGBT power modules usually require short circuit withstand capability. However, not every short circuit has same impact on the power module. Different classifications are done. For example, short circuit type 1 is present when the short circuit occurs before the IGBT turns on.

Are power electronics technology a viable alternative to IGBTs?

In recent years, the potential of power electronics technologies to for various applications, which exhibit lower power loss than IGBTs efficiently use energy and thereby help realize a sustainable society because of the injection enhancement (IE) effect (Figure 1). has been a focus of rising expectations.
