AC DC converters are commonly used in power systems. The LEA75F-18-SNJ2 is a type of AC DC converter, typically suitable for use in high voltage, high speed power supplies. It has the ability to provide a continuous output power of up to 18 kW. It is a single phase, four wire input, three output type AC DC converter. It is also a high frequency, multi-level, three-phase converter for fast charging of electric vehicles with high peak powers.

The LEA75F-18-SNJ2 uses a voltage-source-type topology with three small DC-DC converters that have separate and independent outputs. Each DC-DC converter operates in the voltage fed or power factor corrected (PFC) boost mode. This type of converter increases the input voltage from the AC voltage source to a DC bus voltage to an output voltage, which is proportional to the input voltage.

The working principle of the LEA75F-18-SNJ2 is based on the principle of power factor correction. This is achieved by the use of a PFC controller. This controller controls the voltage of the DC-DC converter in order to have a minimum distortion of the input current. This means that the input current is always close to the input voltage and therefore, the power factor is kept as close to 1 as possible.

The application field of the LEA75F-18-SNJ2 AC DC converter is very wide. It can be used in power supplies, rectifiers, UPS, AC motor controls, and other power applications. It is suitable for use in high frequency power supplies for industrial process control, commercial and medical equipment. Furthermore, this type of converter is used in electric vehicle charging applications as its high peak power allows for a fast charge.

In conclusion, the LEA75F-18-SNJ2 is a high frequency, multi-level, three-phase AC DC converter. It is suitable for use in high voltage, high speed power supplies and can provide a continuous output power of up to 18 kW. It is suitable for use in various power applications, such as power supplies, rectifiers, UPS, AC motor controls, and electric vehicle charging applications. The working principle of the LEA75F-18-SNJ2 is based on the principle of power factor correction.
