Abstract
An apparatus for decreasing speed of an inverter driven inertial load within a time period for use with a dynamic brake across a DC link including a controller for controlling the inverter to regulate the power returned to the brake such that, when a brake command is received, the power is increased during a power-up period while motor deceleration begins and up to a constant power level after which the constant power level is maintained by increasing torque such that the dynamic brake is fully used during the majority of a braking cycle and a method to accomplish the same.
