Abstract
A method for reducing power supply current surges and power supply voltage noise in an electric motor control system. The method limits the rate of change of power to the motor. The rate of change of power is limited by microprocessor firmware. Use of firmware reduces the size and weight requirements of motor control hardware and power supply filtering hardware.
