The IGBT voltage rating closely depends on the input voltage of the equipment in which it will be installed. Table 3-1 lists IGBT voltage ratings and applicable input voltages. Use this table as a reference when selecting modules for a particular voltage application.
When the IGBT module’s collector current increases, consequently so will the VCE(sat) and the power dissipation losses. Simultaneously, there will be an increase in the switching energy, resulting in an increase in the chip and module temperature.
.......................................... This section explains relevant IGBT module selection and application. When using IGBT modules, it is important to select modules which having the voltage and current ratings most suited for the intended application.
When an IGBT is installed and voltage is applied between the collector and emitter while the gate emitter connection is open as shown in Fig. 3-1, depending on changes in the electric potential of the collector, the current (i) will flow, causing the gate’s voltage to rise turning the IGBT on.
It is recommended to keep the collector current at or below the maximum rating for the reasons stated above. This also provides a more economical design. The VGE of an IGBT is rated ± 20V. If an IGBT is subjected to a VGES that exceeds this rated value, then there is a danger that the module might be destroyed.
Photovoltaic (PV) energy has been the largest share of all renewable energy investments in recent years. As the cost of photovoltaic arrays and installation comes down, there will be a greater proportion of PV access. PV inverter is a key component of photovoltaic system.
