Electric power control method and voltage converter therefor in maximum power point tracking control

Abstract

To provide an electric power control method and a voltage converter therefor in maximum power point tracking control (MPPT) related to an optimizer connectable to most commercially available PCSs. With reference to a voltage value of a maximum power point MPPT provided as an apex of a voltage-power curve, an optimum operating point, at which power of solar panels is maximized, is kept at a constant power value by inducing an operating voltage of the power conditioner so as to fall within a flat sub-region of a plateau shape, which has a step formed by straight lines falling down vertically on both low-voltage side and high-voltage side of the voltage-power curve and abutting the slopes of the voltage-power curve, subsequently the operating voltage of the power conditioner is kept in a constant fixed range and outputted to the outside.
