In virtually all industrial control systems, variable frequency drives (VFDs)/inverters are commonly installed at the front end of motors in order to regulate speed and save energy. Based on differing input voltage requirements, inverters are often categorized as low voltage (110V, 220V, 380V, etc.), medium voltage (690V, 1140V, 2300V, etc.), or high voltage (3kV, 3.3kV, 6kV, 6.6kV, 10kV, etc.).
Because VFDs/inverters are critical components in providing power, their operation, performance, and reliability are crucial to maintaining uninterrupted power. This application note focuses on TVS Diodes that can help ensure the reliability and operation of a VFD, even under adverse conditions…
