Power factor correction (PFC) is a technology that is used in a wide range of industries to improve the efficiency, performance and safety of electric power systems. The most effective form of PFC is active PFC which is implemented with a dedicated electronic device, the L6564TDTR. This article will discuss the application field and working principle of this special device.
The L6564TDTR is a high performance, low-cost PFC device intended to be used in high efficiency AC-DC power converters, such as switching power supplies, automotive on-board chargers and hot plug-in computer adapters. The device provides high power factor correction and output power level up to 240W. It offers a robust and flexible solution for manufacturers to design compact, efficient and reliable AC/DC power supplies.
The L6564TDTR is based on a totem pole PFC circuit, a type of Bridgeless PFC circuit where one of the two power MOSFETs is implemented as a transistor. The overall circuit is designed to work in discontinuous conduction mode (DCM). The DCM operation is better suited to power supplies with small power levels since it eliminates the need of snubber circuit used in continuous conduction modes.
The L6564TDTR includes several protection functions such as input overvoltage protection, over-temperature protection, short-circuit protection, open-loop protection and protection against excessive peak current. The device offers an internal current limiter for leading power factor and high efficiency even over a wide load range.
The L6564TDTR works on the principle of controlling the phase between the voltage and current waveforms. It senses the input voltage waveform and then modulates the power switch turning ratio as needed to provide high power factor operation. This is done through the use of an active PFC circuit, which actively controls the voltage and current of the power supply. The L6564TDTR offers high power factor in both light and full load conditions, ensuring a high level of efficiency over a wide range of loads.
The L6564TDTR is a passive device which requires no external programming and is designed to perform without any additional components. This makes it a cost effective solution for integrated PFC designs and is ideal for space-constrained applications as it can be mounted on a narrow PCB.
The L6564TDTR is an ideal choice for AC/DC power converters in applications such as LED lighting, home appliance, industrial equipments, telecom and more. It is also suitable for applications where improved power factor is needed in order to comply with international standards and regulations.
In conclusion, the L6564TDTR is an efficient, low cost and easy-to-use PFC device for numerous AC/DC power converters. It is a robust solution that offers significant improvements in power factor and efficiency, making it an optimal choice for various applications.
