The invention discloses a DSP-based maximum power independent power supply system, which includes a DCDC conversion circuit, which is composed of an energy storage inductance, a power switch tube, a diode, a capacitor and a load resistor; the power switch tube has an output terminal coupled to the energy storage inductance The collector and the emitter coupled to the negative terminal of the voltage; the capacitor is connected in series to the diode conduction terminal, and the load resistor is connected in parallel; after the power switch tube of the DCDC conversion circuit is turned on, the voltage of the power supply is added to the energy storage inductance Above, the inductor current grows linearly, the diode is cut off, and the load is provided by the capacitor; the load resistor continues to work, and an anti-reverse charge diode is provided between the DCDC conversion circuit and the battery pack; when the electricity generated by the solar cell cannot meet the load requirements , the battery pack discharges the load, and when the battery pack discharges, the anti-reverse charging diode conducts forward and reverses.
Description
technical field [0001] The invention relates to the technical field of power supply, in particular to a DSP-based maximum power independent power supply system. Background technique [0002] Solar power supply system is mainly used in solar street lights, solar clocks, solar lawn lights, solar fountains, solar urban landscapes, solar advertising light boxes, solar rechargeable batteries, solar electric vehicles, etc. Solar power is widely used as the preferred renewable clean energy for the following reasons : No polluting gas or impurities are emitted during the process of solar power supplying batteries; solar power supply equipment can be installed in various regions, and there is no need to worry about long-distance transmission and distribution of electricity, which greatly saves the investment of manpower and material resources, application number : Invention patent of 201811559216.6, the current generated by the solar panel charges the battery through the positive pla...
