What does PWM controller mean
The Basic Principles and Application Examples of Pulse Width Modulation
Pulse width modulation (PWM) is a highly effective technique for controlling analog circuits using the digital output of microprocessors.
It is widely used in many fields, from measurement and communication to power control and conversion.
analog circuit
The value of an analog signal can vary continuously, with no limitations on its time and amplitude resolution. A 9V battery is an analog
device because its output voltage is not exactly equal to 9V, but varies over time and can take any real value. Similarly, the current absorbed
from the battery is not limited to a set of possible values. The difference between analog signals and digital signals is that the values
of the latter can usually only belong to a predetermined set of possible values, such as in the set of {0V, 5V}. Analog voltage and current can
be directly used for control, such as controlling the volume of a car radio. In a simple analog radio, the volume knob is connected to a variable
resistor. When turning the knob, the resistance value increases or decreases; The current flowing through this resistor also increases or decreases
, thereby changing the current value that drives the speaker, causing the volume to increase or decrease
accordingly. Like a radio, the output of an analog circuit is linearly proportional to the input.
