RESISTORLESS DYNAMIC MOTOR BRAKING SYSTEM AND METHOD

摘要

Systems and methods are provided for regenerative motor braking. The regenerative braking systems and methods allow the braking torque of a multi-phase motor to be controlled while keeping currents to acceptable levels and without supplying electrical energy back to the voltage source. The regenerative braking systems and methods dissipate energy in the motor windings instead of sending this energy to the voltage source by intelligently switching the low-side switches in the inverter between the ON and OFF states at the commutation frequency while maintaining the high-side switches in the inverter in the OFF state.
