Technical FAQs 4

What is a high power switch in an inverter?

The high-power switches are the most critical component in the inverter as they control the flow of current to the motor to generate motion. As such, the switches' are monitored and protected by sensing their temperature, voltage and current throughout their operation.

What are the benefits of using an inverter?

The inverter benefits not only to prevent the damage or destruction of the power switches, but also prevents high-voltages from being applied to the motor windings, which can also reduce the lifetime of the motor itself. Figure 3-8. Soft Turn-Off Block (UCC21750-Q1, UCC21710-Q1)

How does a traction inverter IC work?

In addition to all of the safety diagnostic features, the IC integrates a primary side and secondary side "active short circuit" circuits to provide the system designer with a secondary path to control a zero-vector state for the traction inverter in the case of motor controller failure.

Why are withstand voltage tests important?

Why are withstand voltage tests important and what are the test methods? Withstand voltage testing is used to check whether a given electrical product or part provides sufficient dielectric strength (i.e., insulation strength) for the voltages to which it may be exposed.
