Abstract
A local power converter may include a controller to manipulate the operating point of a local power converter to cause the power point tracking feature of a central power converter to operate at a point determined by the controller. In some embodiments, the controller can manipulate the operating point of the local power converter by alternating between at least two modes. In some other embodiments, the controller can manipulate the operating point of the local power converter to provide a substantially constant slope. In some other embodiments, the controller can maintain a substantially constant impedance ratio. In some other embodiments, the controller enables perturbations from the power point tracking feature of the central power converter to reach the power source.
