‘Power management’ chip sets improve motor drive design

El Segundo, Calif.—New Accelerator architecture is said to enhance and simplify motor control circuits, whether microprocessor-based or DSP-based, by "partioning the inverter function as an intelligent power management peripheral to the motion system controller." Chip sets consist of mixed signal 0.

El Segundo, Calif.— New Accelerator architecture is said to enhance and simplify motor control circuits, whether microprocessor-based or DSP-based, by “partioning the inverter function as an intelligent power management peripheral to the motion system controller.” Chip sets consist of mixed signal 0.5

Accelerator chips raise reliability by reducing parts count 25% and cut circuit board footprint by 50%. The new architecture claims 10 times wider usable speed range than conventional designs. Low-speed operation of variable-frequency drives (VFDs) is also improved. More precise torque sensing ( www.irf.com .
