The PWM solar controller
refers to the control of the analog circuit in digital output with the microprocessor, 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. Many microcontrollers include a PWM controller.
Basic principles of the PWM solar charge controller
: The impulse is equal and the narrow pulse of the shape is the same as the inertial link. The PWM solar control
principle is to divide the waveform into 6 equals, can be replaced by six square wave equivalents. Classification methods for pulse width modulation include a variety of unipolar and bipolar, synchronous and asynchronous, rectangular wave modulation, and sine wave modulation.
