A4945GLJTR-T is a high-performance, non-dissipative PFC (power factor controller) pre-regulator that combines rectification, inversion, and EMI (electromagnetic interference) filtering into a single device. It is designed to provide power factor correction as well as voltage and current limiting for a variety of industrial and consumer applications. Designed for use with EV chargers, photovoltaic (PV) systems, motor controllers, and other low power applications, the A4945GLJTR-T is a complete power factor and voltage protection solution.

The A4945GLJTR-T integrates a rectifier, inverter, and EMI filter into a single device, eliminating the need for a separate rectifier and inverter. With an input voltage range from 0V to +380V, the device can be used in applications where a traditional rectifier/inverter setup may not be feasible due to space or cost constraints. The A4945GLJTR-T also includes a low power voltage regulator and current limiting circuit, eliminating the need for separate components.

The A4945GLJTR-T’s goal is to produce a steady, continuous output voltage that can be accurately regulated. This is achieved through its power factor control loop, which measures the power factor of the incoming AC signal and adjusts the output voltage accordingly. This circuit delivers a high degree of power factor correction with very little ripple. The current limiting feature ensures that the output current never rises above a safe level, protecting against overloads. The A4945GLJTR-T also includes an EMI filter that reduces high-frequency noise generated by the incoming AC line, allowing for a clean power output.

Applications for the A4945GLJTR-T can be divided into two categories. The first category is Motor Drivers, Controllers, and other industrial applications. The high power handling capacity and precise voltage regulation of the A4945GLJTR-T make it a good choice for applications such as drives, controllers, and PLCs. The second category is consumer applications, such as EV chargers and PV systems. The A4945GLJTR-T’s integrated power factor correction and current limiting features make it ideal for these applications. Additionally, its low power consumption makes it an ideal choice for applications that need to stay power efficient.

In summary, the A4945GLJTR-T is a versatile, high-performance PFC pre-regulator suitable for a wide range of applications. Its integrated rectifier, inverter, and EMI filter eliminate the need for separate components, while its precise voltage regulation and power factor correction make it ideal for demanding applications. It is suitable for Motor Drivers, Controllers, EV chargers, and PV systems, as well as a variety of other low power applications. As a result, the A4945GLJTR-T is an attractive choice for power system designers looking for improved performance and power efficiency.
