49 Power Quality Drives ROBICON The Sine of Quality Dual-Frequency Braking  Unlike DC injection, this approach provides much higher torque per ampere, and permits continuous estimation of motor speed.  The new method causes extra losses to be induced in the motor by applying a second set of three- phase voltage vectors to the motor in addition to the normal set of voltage vectors used for speed control.  The energy returned to the DC link by the normal vector set is used to create the second set of loss- inducing vectors, which dissipate that energy in the motor.
