Abstract

The invention discloses a MPPT (Maximum Power Point Tracking) solar controller, which overcomes defects that high heat is generated during the working process and the working efficiency is low as the current MPPT (Maximum Power Point Tracking) solar controller includes an isolation transformer. According to the controller, a boosting circuit carries out boosting on an input voltage according to one boosting control signal and constant current output is then carried out, a high frequency switch circuit receives a driving signal and sends a current feedback signal to a constant current output control circuit, and when an output sampling voltage is not higher than a reference voltage, the constant current output control circuit sends a boosting control signal to the boosting circuit and sends a driving signal to the high frequency switch circuit according to the input sampling voltage and the current feedback signal. According to the embodiment of the invention, high heat is not generated during the working process, and no high cooling demands is needed for the product.

Description

technical field [0001] The invention relates to a solar controller, in particular to an MPPT solar controller. Background technique [0002] The maximum power point tracking (MPPT) solar controller can detect the maximum output power of the solar panel in real time, and track the highest voltage and current value (VI), so that the system can charge the battery with the highest efficiency. [0003] At present, the photovoltaic power generation step-up technology with MPPT is output after being boosted by the isolation transformer. However, the isolation transformer has a large volume, and the windings need to be wrapped with insulating glue. In addition, the isolation transformer will generate a lot of heat when it is working, so it has high requirements for the heat dissipation of the MPPT solar controller. Moreover, the withstand voltage requirements for other components in the MPPT solar controller are also relatively high. Contents of the invention [0004] The techn...
