• PWM 10A Speed Controller About PWM:

• Pulse-width modulation (PWM), or pulse-duration modulation (PDM), is a method of reducing the average power deliver by an electrical signal, by effectively chopping it up into discrete parts. The average value of voltage (and current) fed to the load is control by turning the switch between supply and load on and off at a fast rate. The longer the switch is on compare to the off periods, the higher the total power supplied to the load. Along with maximum power point tracking (MPPT), it is one of the primary methods of reducing the output of solar panels to that which can be utilize by a battery. PWM is particularly suited for running inertial loads such as motors, which are not as easily affected by this discrete switching, because their inertia causes them to react slowly. The PWM switching frequency has to be high enough not to affect the load, which is to say that the resultant waveform perceive by the load must be as smooth as possible.
• In electronics, many modern microcontrollers (MCUs) integrate PWM controllers expose to external pins as peripheral devices under firmware control by means of internal programming interfaces. These are commonly use for direct current (DC) motor control in robotics, switch-mode power supply regulation, and other applications.
