The LFP100F-24-GY is a product category of AC DC converters, specifically a 24 Vdc / 100 W output device. It provides a wide input voltage range of 85–264 Vac/125–370 Vdc, thereby enabling operation in some general purpose and wide voltage applications. It includes a built-in PFC function and a high efficiency of up to 89%. It operates in a temperature range of -20 to +85°C.

The AC/DC converter provides efficient, high-power, cost-effective solutions for specialty and general purpose applications, such as medical equipment, industrial process control, or white goods appliances. It can be used for multi-stage power applications, such as laser systems, communication equipment, and general laboratory use. The small size and high efficiency make it versatile in many applications.

The LFP100F-24-GY AC/DC converter comes with multiple protection features, including over-voltage, over-current, and short circuit protection. It also has electronic overload protection, over temperature protection, and over-voltage protection with dynamic current limit. All these protection features make the LFP100F-24-GY ideal for applications where reliability is critical.

When it comes to working principle, the LFP100F-24-GY converts AC voltage to DC voltage. This type of AC/DC converter is also known as a bridge converter, which uses four semiconductor switches to convert the AC voltage into DC voltage. The bridge converter has four operating phases, which are discontinuous conduction mode (DCM), continuous conduction mode (CCM), quasi-resonant mode, and full-resonant mode. In the DCM, the current flow is intermittent while in CCM, the current more smoothly.

During the DCM operation, the current interrupts when the current reaches the minimum level and in the CCM, the current will remain more constant as it passes the zero current level. In the full-resonant mode, the current shows zero values at its peak and dip levels and this results in higher efficiency and better power factor. The quasi-resonant mode uses the ripple of the output current to adjust the power switches. This can help reduce EMI and RFI emission and make the converter more efficient.

The LFP100F-24-GY AC/DC converter is a reliable, efficient, and cost-effective way to convert AC voltage to DC voltage. It is suitable for various power supply applications, including medical and industrial equipment, white goods, and multi-stage power applications. The built-in protection features, high frequency operation, and low power consumption make it a great choice for many applications. The four operating modes and the adjustable output voltage can also help to improve the efficiency and performance of the power converter.
