AC-DC Converter: Making the Switch from Alternating to Direct Current
著者： ZYGパワーモジュール Time： 2023-4-13
AC-DC converters, also known as rectifiers, are electronic devices that convert alternating current (AC) to direct current (DC). This is important because most electronic devices, such as computers and televisions, require DC in order to operate. AC-DC converters are used extensively in power supply applications and are a common component in many electronic devices.
The process of AC-DC conversion begins with the rectification of the AC signal. Rectification is the process of converting the AC signal into a DC signal by removing the negative portion of the waveform. This is done using a rectifier diode, which allows current to flow in only one direction. The result is a pulsating DC signal that has a voltage equal to the peak value of the AC signal.
The pulsating DC signal is then filtered using a capacitor to remove the high-frequency ripples. The capacitor charges when the voltage is high and discharges when the voltage is low, resulting in a smoother DC output. The final output voltage is regulated using a voltage regulator, which ensures that the output voltage remains constant despite fluctuations in the input voltage or load.
AC-DC converters can be classified into two types – uncontrolled and controlled rectifiers. Uncontrolled rectifiers use diodes to rectify the AC signal and are commonly used in low-power applications. Controlled rectifiers use thyristors, which are solid-state switches, to control the rectification process. This allows for more precise control over the output voltage and current, making them ideal for high-power applications.
The efficiency of an AC-DC converter is an important factor to consider when designing a power supply. Efficiency is defined as the ratio of output power to input power and is expressed as a percentage. A higher efficiency means less power is wasted as heat and more power is delivered to the load.
In conclusion, AC-DC converters are essential components in modern electronics and power supply applications. They convert AC to DC and regulate the output voltage to ensure a steady supply of power. The use of controlled rectifiers allows for precise control over the output voltage and current, making them ideal for high-power applications. Efficiency is an important factor to consider when designing a power supply, as it determines how much power is delivered to the load and how much is wasted as heat.

An AC-DC converter, also known as a rectifier, is an electronic device that is used to transform alternating current (AC) into direct current (DC). This process is essential in many applications where DC voltage is required, such as in electronic devices and power supplies. The conversion process involves a diode bridge rectifier that allows the AC current to pass through in only one direction, effectively converting it into DC voltage. This rectifier is made up of four diodes that are arranged in a specific pattern to create a bridge circuit. During the positive half-cycle of the AC voltage, one pair of diodes conducts and allows the current to flow through them, while the other pair of diodes is reverse-biased and...
