  • How to solve the inverter under-voltage fault The drive (VFD) under-voltage protection of ordinary low-HP drives is based on the measured voltage on the DC bus of the drive unit instead of the input AC voltage. It is important to be aware of this fact to help troubleshoot. Any event that may cause the DC link voltage to drop may cause a DC link undervoltage fault event. This guide will help you resolve undervoltage ...

  • Three ways to test the temperature rise of thyristor modules. If a thyristor module is used for a long time, its temperature will rise. If the temperature is too high, it will be easily damaged and its service life will be reduced. This requires us to understand the test Heating method: 1. Determination of the ambient temperature of the thyristor module: Place a thermometer, thermometer ...

  • What is a triac and how does it work? A bidirectional thyristor is a triac, which is an abbreviation of a thyristor, sometimes called a thyristor. Before understanding the bidirectional thyristor, first understand the unidirectional thyristor. It is a high-power semiconductor switching device. They all have three electrodes, namely anode A, cathode K, and control electrode G. Unidirectional crystal ...
