Research on Adjustable Energy Consumption Braking System

Energy consumption braking is widely used in the field of air winch. When the BLDCM (Brushless Direct Current Motor) is in the reverse braking state, the energy-consuming braking circuit reduces the bleeder power of the bleeder resistor and the volume of the energy-saving brake bleeder resistor by adjusting the duty cycle of the switching tube. In this paper, the Matlab simulation model is used to verify that reducing the duty cycle can reduce the heating power of the bleeder resistor to reduce the volume of the bleeder resistor, thereby increasing the controller power density.
