Introduction of AC/DC Converters

AC/DC converters are electrical devices that convert alternating current (AC) to direct current (DC). AC/DC converters use the principles of induction and rectification to achieve this transformation. Generally, AC/DC converters are used to power electronic equipment and appliances, both in commercial and domestic settings.

LEA150F-18-GR Application Field and Working Principle

The LEA150F-18-GR is an AC/DC converter that is part of the LUXOREX LEA series. The LEA150F-18-GR has a wide variety of applications, ranging from providing power to automotive and health care equipment to powering consumer electronics such as mobile phones, digital cameras, and video games.The LEA150F-18-GR has an input voltage range of 120 VAC to 300 VAC and an output voltage of 18V DC, making it suitable for applications requiring higher output voltages. It is also capable of delivering up to 4 amperes of current without any external components.The LEA150F-18-GR makes use of a four-stage, bridgeless PFC (pulse-width modulation) topology to achieve full-bridge rectification while providing good efficiency. This allows it to achieve up to 91.5% efficiency with no additional components.In operation, the LEA150F-18-GR will first convert the AC line voltage into a DC intermediate voltage, which is then used to charge a DC capacitor. The DC capacitor then feeds a high-frequency switch, which produces a switching signal that is used to control the PFC converter. The PFC converter then rectifies the AC line voltage into a DC output voltage that is regulated by a voltage feedback loop.The LEA150F-18-GR is also protected against overvoltage, overcurrent, and short-circuit conditions through the use of an on-board protection circuitry. This allows the converter to operate safely and reliably in a variety of applications.Overall, the LEA150F-18-GR is a reliable and efficient AC/DC converter that is suitable for a variety of applications, including powering automotive and health care equipment and consumer electronics. It makes use of a four-stage, bridgeless PFC (pulse-width modulation) topology to achieve full-bridge rectification while providing good efficiency. The LEA150F-18-GR also includes on-board protection circuitry to ensure safe and reliable operation.
