AC-DC converters have become increasingly popular in the last twenty years due to their efficiency, small size and cost. They are especially useful in applications where frequent and reliable power is required, such as in medical equipment, industrial machinery and motor control. AC-DC converters are classified according to their working principle, with two main types: linear and switching.

Linear AC-DC Converters

Linear AC-DC converters are based on the concept of linearity, which states that the output voltage is directly proportional to the input voltage. In other words, for any given input voltage, the converter will produce an equal output voltage with no change in frequency or phase. Linear AC-DC converters use a transformer to convert alternating current (AC) into direct current (DC). The transformer reduces the voltage to the desired levels, and the rectifier bridges convert the AC output to DC.

Linear AC-DC converters are typically used in applications where a constant voltage is required, such as audio amplifiers, computer power supplies and laboratory instruments. They are also used in applications that require high efficiency, such as rectifiers for electric motors. Linear AC-DC converters have a linear characteristic, which makes them easy to control and adjust. However, they require large transformers, which can be an issue in small spaces.

Switching AC-DC Converters

Switching AC-DC converters are based on the concept of switchability, which states that the output voltage can be changed by varying the duty cycle of the switches. In other words, for any given output voltage, the converter can be adjusted to produce a different voltage or current independently of the input voltage. This type of converter uses a pulse width modulator (PWM) to switch the voltage between the input and output. The PWM can be tuned to control the voltage or current of the output according to the application’s requirements.

Switching AC-DC converters are typically used in applications where high efficiency and low noise are essential. They are especially useful in motor control applications, as they can control the motor speed or torque easily and accurately. They are also used in automated assembly lines and robotic systems due to their stable, predictable output. Switching AC-DC converters are more efficient than linear AC-DC converters, but require larger components and more complicated control circuits.

2938633 Application Field & Working Principle

The 2938633 application field is AC DC converters. This type of converter is used to convert alternating current (AC) into direct current (DC). The two main types are linear and switching converters. Linear converters use a transformer to reduce the voltage to the desired levels and rectifier bridges to convert AC to DC. Switching converters use a pulse width modulator (PWM) to switch the voltage between the input and output, providing high efficiency and low noise. Both types of converters are widely used in applications that require frequent and reliable power, such as medical equipment, industrial machinery and motor control.
