  • Patent number: 11721997
    Abstract: This disclosure describes, in part, techniques for reducing pulsating currents of internal power sources, such as batteries. For example, a device may include a power source, a load, and a control device located between the power source and the load. The control device may include a power converter that is configured to maintain a constant input current from the power source and output a pulsating current to the load. While regulating the power, the control device may determine whether an average output power is different than a reference power. If the average output power is equal to the reference power, then the control device may cause the power converter to maintain the constant input current. However, if the average output power is different than the reference power, then the control device may cause the power converter to alter (e.g., decrease/increase) the input current being received from the power source.
