AC/DC converters, also known as rectifiers, are electrical equipment which convert Alternating Current (AC) to Direct Current (DC). This conversion process can either be constant voltage (AC/DC), a controllable type of converter which can be used for regulation and control purposes, or a constant current (AC/DC) converter, which are mostly used to provide a stable current source to an electrical circuit or load. The LEA75F-5-S is an AC/DC converter that is used mostly in telecommunications and automotive applications.

The LEA75F-5-S is a 3-phase AC/DC converter and it contains five terminals, named U, V, W, P and H, and the input voltage should be 380V. Using these three phase AC inputs, it can provide DC output voltage from DC 48V to DC 400V. It can output power of up to 75kW and switching frequency of up to 300kHz. This AC/DC converter is fully isolated and it provides isolation voltage of up to 1,500V. It also has an internal heatsink which ensures thermal protection. Moreover, the LEA75F-5-S is resistant to electromagnetic interference (EMI) and various industrial vibrations.

The working principle of the LEA75F-5-S is based on the control of the energy transfer. It uses a three-phase bridge rectifier circuit which is controlled by insulated gate bipolar transistors (IGBTs). These IGBTs act as a switch and depending on the voltage of their gate, they are turned on or off. When they are in their "on" state, a current passes and energy is transferred, and when they are in their "off" state, no current passes and no energy is transferred. The switching of these IGBTs is controlled by the controller of the LEA75F-5-S, and this switching can be done to different frequencies, depending on the needs of the application.

This AC/DC converter has a wide range of application fields. It is mostly used in the telecommunications and automotive sectors, and the most common applications are battery charging systems, DC converters for motor control, uninterruptible power systems (UPS), UPS for automobiles, renewable energy systems, automatic voltage regulator (AVR) systems, electric vehicle (EV) charging systems and industrial robotics.

The LEA75F-5-S is a powerful AC/DC converter; it is capable of providing powerful output power, high efficiency, and good EMI/RFI features. It is widely used in a wide range of applications and is preferred by many users due to its high performance and reliability. It is also a cost-effective solution compared to other AC/DC converter solutions, making it a great choice for many industrial applications.
