Abstract:
1. A maximum power point tracking circuit for a solar panel, the tracking circuit comprising: a) a real-time power calculator configured to receive a real-time output voltage and a real-time output current of said solar panel, and to generate therefrom a real-time power of said solar panel; b) a memory power generator configured to generate a memory power based on said real-time power; c) a comparing circuit configured to compare said real-time power against said memory power; d) a reset circuit configured to receive said real-time output voltage of said solar panel; e) a control signal generator configured to generate a controlling signal based on output signals of said comparing circuit and said reset circuit, wherein a trend of said controlling signal is maintained when said real-time power is increasing, and wherein said trend of said controlling signal is changed when said real-time power is decreasing; and (f) said controlling signal being configured to recover to a previous value that occurred when said real-time power was increasing in response to said real-time output voltage being higher than an average output voltage by at least a predetermined value and said real-time power decreasing.
