Pulse Width Modulation (PWM) Techniques for DC Motor Control and Power Conversion

Pulse Width Modulation (PWM) is a powerful and widely-used technique in modern electrical engineering, particularly for controlling the speed of DC motors and optimizing power conversion. By adjusting the width of the pulses in a signal, PWM allows for efficient control of motor performance, delivering precise regulation of motor speed and torque. Additionally, it plays a crucial role in power conversion systems, such as inverters and DC-DC converters, by enabling better efficiency and reducing energy losses. This technique has become fundamental in various applications, from robotics to renewable energy systems, where efficient energy management and smooth motor operation are key to achieving high performance.  There are several ways to control the speed of DC motors, but one of the easiest and most efficient methods is using Pulse Width Modulation (PWM) . Before we dive into how PWM works, let's first understand how a DC motor operates. How a DC Motor Works The Permanent Magnet DC M…
