48v electric vehicle controller output motor is alternating current?
The output motor of the 48V electric vehicle controller is direct current. The working principle of the controller is to chop the direct current so that the peak voltage is almost equal to the battery voltage, and the interval between the waves becomes the key. By adjusting the interval between the waves, the average voltage of the output can be changed, thereby changing the output power.
