1. The drive voltage of inverter IGBT is usually 15V to 20V.
2. This is because IGBTs (insulated gate bipolar transistors) require a high driving voltage to ensure their proper operation.
A voltage of 15V to 20V can provide enough current to turn the IGBT on and off. 3. In addition, the choice of drive voltage also depends on the specific requirements of the application, such as the size of the current and power.
In some special cases, the drive voltage may be different and needs to be adjusted according to the specific situation.
