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.
