What is the role of IGBT in an inverter?
As a power device, IGBT (insulated gate bipolar transistor) plays the role of power conversion and energy transmission in the inverter, and is the heart of the inverter. At the same time, IGBT is one of the most unreliable components in the inverter, which is very sensitive to the temperature and current of the device.
How much damage does a photovoltaic inverter cause?
When the optimal PV system capacity ratio and power limit value are taken, the annual damage of the IGBT in the photovoltaic inverter is 0.847% and the net increase of power generation is 8.31%, realizing the increase of photovoltaic power generation while the annual damage of IGBT and power generation loss due to power limit is relatively low.
Are insulated-gate bipolar transistors a good choice for solar inverter applications?
For solar inverter applications, it is well known that insulated-gate bipolar transistors (IGBTs) ofer benefits compared to other types of power devices, like high-current-carrying capability, gate control using voltage instead of current and the ability to match the co-pack diode with the IGBT.
How to improve PV inverter lifetime?
In response to this problem, the literature proposed a novel control strategy to limit the power generation, thereby improving the PV inverter lifetime. For a specific photovoltaic inverter system, there should be an optimal PV system capacity ratio and power limit value, taking into account inverter damage and increasing power generation.
Does the topology of a PV inverter affect the damping ability?
The topology of the inverter also affects the damping ability provided by PV generation . In most cases, voltage-source converters perform better than current-source converters in terms of small-signal stability. It was also found that the location and size of the PV injection influence the damping of the critical modes.
