PWM is the pulse width modulation, which means that the digital output of the microprocessor is controlled to control the analog circuitry, which is a method of digitally encoding an analog signal level. Control the analog circuit in a digital manner, it can greatly reduce the cost and power consumption of the system.

The electrical structure of the PWM solar controller is relatively simple, mainly consisting of a power main switch, a capacitor, one drive plus a protection circuit, actually equivalent to a switch, connecting the components and batteries together, the voltage of the component is pulled down A voltage close to the battery pack.
