What is a PWM Solar charge controller?

Pulse Width Modulation (PWM) is the abbreviation of "Pulse Width Modulation" in English, referred to as Pulse Width Modulation.

It is a very effective technology to control analog circuits by using the digital output of microprocessors, and is widely used in many fields such as measurement, communication, power control and conversion. An analog control method, which modulates the bias of the gate or base of the transistor according to the change of the corresponding load to realize the change of the output transistor or the conduction time of the transistor of the switching regulated power supply. This method can make the output voltage of the power supply work. remain constant as conditions change.
Pulse Width Modulation (PWM) is a method of digitally encoding analog signal levels.
