Features of MPPT
The main functions of the MPPT controller: detect the DC voltage and output current of the main circuit, calculate the output power of the solar cell array, and realize the tracking of the maximum power point. Dither resistor R is in series with the MOSFET. When the output voltage is basically stable, the current disturbance is generated by changing the average current flowing through the resistor by changing the duty cycle of the MOSFET. At the same time, the output current and voltage of the photovoltaic cell will also change accordingly. The output power and voltage of the photovoltaic cells before and after perturbation were measured to determine the direction of perturbation in the next cycle. When the interference is in the right direction, the output power of the solar panel increases. The loop continues to perturb in the same direction, instead, it perturbs in the opposite direction. Repeated disturbance and observation in this way makes the output of the solar photovoltaic panel reach the most objective power point
The utilization of wind energy is mainly to convert the kinetic energy of the atmosphere into other forms of energy. Among them, wind power is the most important form of wind energy utilization.
1. Wind lift water
It is widely used in water-lifting operations such as farmland irrigation, seawater salt production, seawater aquaculture, drinking water for humans and animals, and grassland improvement, and has achieved good economic benefits.
2. Wind Power
This is the main form of wind power generation, and wind farms (wind farms) are an important sign that wind energy utilization has entered the practical stage
3. Sailing aids navigation
Since the 1970s, many countries have successively carried out research on modern sailing ships. At present, international commercial ships have developed from 1,000-ton to 10,000-ton class. The fuel saving index is 20-30%, but the cost is only comparable to that of ordinary ships
4. Wind heating
The mechanical energy of the output shaft of the wind wheel is directly converted into thermal energy, and its conversion efficiency is high, which can be used for greenhouse heating, aquaculture and drying, etc.
