Frequency inverter

Frequency inverter Technology, so, welcome to the world of the new frequency inverter.

This has been an evolution; but it has not been without its trials and tribulations. The first frequency inverters were not very good, to say the least. The transistors and capacitors had been one of the biggest problems in many of the earlier designs, but the arrival of the IGBT was a real breakthrough in the advancement of the modern day frequency inverter.

With each new year the switching rates of the transistors becomes better and better; and so does the performance and reliability of the inverters in the marketplace, which have now become somewhat of a commodity.

Buy a motor and inverter from the corner store put them together and off you go.
Yes it can be almost that easy - but is this all there is to the inverters industry today?
