Our product is medium voltage (4160V) variable frequency drive. It consists of 9~24 power cells depending on the power level of the load. Each power cell has a control board with a DSP56F807 and an Altera EPLD on it. The DSP talks to the EPLD via SPI port and the EPLD talks to a master control board via a fiber optic cable. The drives that we have DSP watch-dogged is used in a coal po...
