摘要：We describe a power conditioning unit with maximum power point tracking(MPPT) for a dc power source, in particular a photovoltaic panel. A power injectioncontrol block has a sense input coupled to an energy storage capacitor on a dc link and
controls a dc-to-ac converter to control the injected mains power. The power injectioncontrol block tracks the maximum power point by measuring a signal on the dc link whichdepends on the power drawn from the dc power source, and thus there is no need tomeasure the dc voltage and current from the dc source. In embodiments the signal is aripple voltage level and the power injection control block controls an amplitude of an accurrent output such that an amount of power transferred to the grid mains is dependenton an amplitude of a sinusoidal voltage component on the energy storage capacitor.
