The fundamental function of the IGBT is rather simple. A positive voltage UGE from gate to emitter turns on the MOSFET. Then, the voltage connected to the collector can drive the base current through the bipolar transistor and the MOSFET; the bipolar transistor turns on and the load current can flow.
.......................................... 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.
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.
ctor parameters and gate drive details. Much of the performance of an individual IGBT in a specific application is determined by the mounting, printed wiring board, and surrounding component parameters, such as for inductors and transformers. To optimize a design, those components and the specific gate drive waveforms for the gates must be t
The purpose of the Application Note is to provide an explanation of the parameters and diagrams given in the datasheet of industrial IGBT modules. It helps the designer of power electronic systems to use the datasheet properly and provides background information.
