The basic principle of pwm solar charge control works :

The basic principle of pwm control is to control the on-off of the switching device of the inverter circuit, so that the output terminal can obtain a series of pulses with equal amplitude, and these pulses are used to replace the sine wave or the required waveform.

A plurality of pulses are generated in a half cycle of the output waveform, and the equivalent voltage of each pulse is a sine waveform, and the obtained output is smooth and has few low-order harmonics. The width of each pulse is modulated according to certain rules, which can not only change the size of the output voltage of the inverter circuit, but also change the output frequency.

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. The PWM signal is still digital because at any given moment, the full-scale DC supply is either fully present (ON) or completely absent (OFF).
The voltage or current source is applied to the analog load in a repetitive pulse train of ON or OFF. When it is on, it is when the DC power supply is added to the load, and when it is off, it is when the power supply is disconnected. Any analog value can be encoded using PWM as long as the bandwidth is sufficient.
