PWM solar controller electrical structure is relatively simple

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.
