These drives facilitate precise control over motor speed, leading to improved energy efficiency, reduced wear and tear, and enhanced process control. Components of Electrical AC Drives: Rectifier: The rectifier converts incoming AC power to DC power. This is a crucial step in the process as the DC power is easier to control and manipulate. DC Bus: The DC bus acts as a buffer, smoothing out fluctuations in the incoming power and providing a stable DC voltage. Inverter: The inverter converts the stable DC power back into AC power, but with variable frequency and voltage. This is the stage where the speed control of the motor is achieved. Controller: The controller, often equipped with a microprocessor, regulates the frequency and voltage supplied to the motor based on the desired speed and torque settings. Working Principles: Electrical AC Drives operate on the principle of Pulse Width Modulation (PWM). The controller adjusts the width of the pulses in the waveform, effectively controlling the amount of power
