PMW, also known as Pulse-Width Modulation, refers to a technique used in electronic systems to control the average power delivered to a load. Some common synonyms for PMW include pulse-duration modulation, duty cycle modulation, and pulse-width control. These terms all essentially refer to the same concept of altering the width of pulses in a signal to regulate power output. Other related words may include PWM controllers, which are devices used to regulate the modulation process, or PWM signals, which are the actual output of a PMW system. Overall, these terms are important to understand for anyone working in electronics or power management, as PMW is a common and versatile method for controlling electrical systems.
