Abstract
The invention provides an analog photovoltaic power circuit with auto zero calibration, which judges whether the current trend or voltage trend has the same direction as or different direction from the power trend, and adjusts an input/output power conversion accordingly, so that an input current approaches to an optimum current corresponding to a maximum power point, in which the judgments of the current trend, voltage trend and power trend is calibrated with auto-zero circuitry.
