Making the Choice between Low Voltage and Medium Voltage Drives Variable Frequency Drives

Historically, the task for low voltage users has been relatively straightforward; choose one supplier from many in the market, based on a number of criteria including price, reliability, functionality, and communications. However, for a drive control solution for larger industrial loads, the situation is not so clear-cut. Until quite recently, most engineers faced with a highpower application would choose a low voltage (LV) drive system working at very high levels of current.
