LFP300F-36-JY

LFP300F-36-JY application field and working principle

The LFP300F-36-JY is a highly efficient AC/DC converter with an extremely low switching frequency, high voltage withstand capability, and high output power. It has been developed to be used in a variety of applications including energy saving, energy conversion, automation and motion control, high frequency switching, power supply rectification, motor control, and power distribution systems.

The AC/DC converter provides a direct current (DC) output voltage that is regulated to a given voltage value, such as 12V, 24V, or 36V. The input voltage can be either an AC line, such as 230VAC or 400VAC, or a DC input with a voltage range of between 10V-480V. The AC/DC converter takes advantage of the latest high-frequency converter technology to achieve very high efficiency, low noise, and a wide input voltage range.

At the core of the AC/DC converter is a high frequency full bridge topology, which consists of two pairs of MOSFETs operating in a synchronous rectification operation. The bridge rectifier provides conversion of the AC input voltage to a DC voltage, while the synchronous rectifier handles the power conversion efficiency through the control of the current flow. The PFC (Power Factor Correction) feature works together with the low-frequency synchronous rectification to improve the overall power efficiency by minimizing harmonic distortion of the input voltage.

The AC/DC converter also includes a built-in over-voltage protection circuit and temperature shutdown circuit to protect it from any potential damage. The over-voltage protection circuit will monitor the current and voltage levels, and will shut down the device if these levels exceed the allowable limits. The temperature shutdown will be triggered if the temperature of the AC/DC converter exceeds its maximum temperature. The AC/DC converter also includes a microcontroller for monitoring and control.

The AC/DC converter is highly reliable and has been extensively tested through the full operating voltage range. With its high switching frequency, high voltage withstand capability, and high output power, this AC/DC converter is an ideal choice for energy saving, energy conversion, automation and motion control, high frequency switching, power supply rectification, motor control, and power distribution systems.
