AC DC converters have been extensively used in various areas such as medical devices and automotive field. The LFA240F-36-GR AC DC Converter is a power module with high efficiency, wide input voltage range, short-circuit protection, and over-voltage protection. In this paper, the application field and working principle of the LFA240F-36-GR AC DC Converter are expounded, and their features and advantages are described.

The LFA240F-36-GR AC DC Converter is mainly applied to require long time stable and reliable discharging and to have the isolation of high voltage and low voltage. It has a wide input range so that it can be used in apower supply system with large load and can provide continuous power output. Therefore, it can be used for the power supply of on-board instrumentation, audio amplifier and video display device, as well as the power basis of commercial test instruments and electronic devices.

The working principle of the LFA240F-36-GR AC DC Converter is based on a bridge circuit, which is composed of two pairs of switching elements, one pair of diodes, one selected capacitor, one pulse transformer and two output filters. In the bridge circuit, the switching elements convert the AC power to pulse width modulation (PWM). The diodes provide the isolated rectification. The capacitor filters the input current whilst the transformer isolates the PWM signals from the AC power source. The output filter cleans the PWM and converts it to DC power.

The LFA240F-36-GR AC DC Converter can efficiently control the output voltage and current so that it can meet the requirements of large load, light load, over-load, and so on. The input voltage remains unchanged when the load and output voltage fluctuates. It has wide input voltage range from 9- 36V, maximum output current 200mA and short-circuit protection. It also has the functions of over-voltage protection, over-temperature protection and isolation protection.

The LFA240F-36-GR AC DC Converter also has advantages in terms of accuracy. Its output stability is high and its accuracy can reach 0.5%. Moreover, it has a low ripple and noise that can reach about 2% of the full scale. Its efficiency is also high since it has low input and output current ripple that make it power saving.

In conclusion, the LFA240F-36-GR AC DC Converter has wide input voltage range, short-circuit protection, over-voltage protection, and other features that make it suitable for commercial test instruments and power supply of on-board instrumentation. It also has the advantages of high accuracy, low ripple and noise, as well as power saving. Therefore, the LFA240F-36-GR AC DC Converter can be applied in various areas such as medical devices and automotive field.
