Abstract
A method for braking a washing machine in accordance with the present invention comprising the steps of: setting up an initial data of a duty ratio corresponding to a detected speed and a rotating position; discharging a voltage of the capacitor filter during a duty-on cycle according to the duty ratio set up in the preceding step; and charging a voltage to the capacitor filter during duty-off cycle when the duty-on cycle of the preceding step is finished. As described above, the dynamic braking resistor is not used in the method for braking the washing machine according to the present invention so that the size and the production cost are reduced.
