Adopt maximum power point tracking (MPPT) technology to ensure that the solar cell is in the maximum power output state under different environmental conditions, and the energy conversion efficiency is increased by 20-30%.
PWM is a control method applicable to many power supply topologies. Power supplies of any topology have a very wide range of uses and can be described as ubiquitous; and PWM has a wide range of applications.
Narrow pulses with equal impulse but different shapes have the same effect when applied to the link with inertia. According to the PWM control principle, the waveform is divided into 6 equal parts,
The cost of the MPPT controller is higher than that of the PWM controller, even several times that of the PWM controller, but the charging efficiency of the MPPT controller is higher,
One of the advantages of PWM is that the signals from the processor to the controlled system are all in digital form, without the need for digital-to-analog conversion.
Simply put, PWM is a method of digitally encoding the level of an analog signal. Through the use of high-resolution counters, the duty cycle of the square wave is modulated to encode the level of a specific analog signal.
