6 FAQs about Voltage source inverter IGBT selection current value

What is the IGBT voltage rating?

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.

Which IGBT module should I Choose?

.......................................... 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.

How is voltage measured in IGBT module?

The DC link voltage is measured using a voltage divider across the DC link and isolated amplifier AMC1311. The IGBT module temperature is measured using the NTC integrated inside the IGBT module. A voltage divider is formed using an external resistor and the NTC. The voltage drop across the NTC is sensed using isolated amplifier AMC1311.

What voltage do IGBT gates need?

These control signals are usually the outputs of a MCU and are at low voltage levels such as 3.3 V or 5 V. The gate controls required by the IGBTs are in the range of 15 to 20 V and need high current capability to be able to drive the large capacitive loads offered by the IGBT gates.

What happens if the IGBT module's collector current increases?

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.
