6 FAQs about [Inverter power withstand voltage selection]

How to choose an inverter?

Generally, select an inverter which fits the maximum applicable motor capacity of the selected motor. After selecting an inverter, check if it meets with all of the following conditions. If it does not, select an inverter that has a one class larger capacity and check the feasibility again.

What is inverter power switch short-circuit protection?

Inverter power switch short-circuit protection is fully integrated. A desaturation detection circuit is embedded in both the high- and low-side output stages and monitors the IGBT collector-to-emitter voltage by means of an external high voltage diode.
