Abstract

See full text

A system continuously drives a motor during normal and power failure operating conditions. A regenerative drive delivers power to the motor from a main power supply during the normal operating condition and from a backup power supply during the power failure operating condition. A controller operates the regenerative drive to provide available power on the regenerative drive to the backup power supply during the normal operating condition.
