5 FAQs about [Inverter high frequency will cut off power protection]

How does an inverter protect a motor?

When the motor's current exceeds 150% of the rated value for 3 seconds, or 200% of the rated current for 10 microseconds, the inverter protects the motor by shutting down. Open-phase Protection. Monitor the output voltage.

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.

What is frequency inverter?
