PFS713EG

Power Factor Correction (PFC) is a method for improving the power factor in an electric power system to reduce losses due to inductive loads. It is achieved by using a device called a power factor controller (PFC). It is commonly used in high power installations such as industrial plants, hospitals and other commercial buildings. The PFC713EG is a voltage-controlled PFC power factor controller capable of operating at up to 190VAC. It has low quiescent current, low external component count, and a wide operating temperature range of -40℃ to +150℃.

The PFC713EG is a buck-boost power factor controller, meaning it can boost the input voltage and reduce the input current. This provides a higher power factor, reduced power losses and improved power system efficiency. The PFC713EG also has excellent input current waveform shaping capability to reduce common mode EMI. It is also equipped with a frequency jittering feature to reduce EMI from conducted EMI.

The PFC713EG is typically used for AC-DC power systems with rectified output and active EMI reduction. It is used in a wide range of applications such as LED lighting, industrial motor drives, air-conditioners, refrigerators, washing machines, electric vehicles and more. The PFC713EG can be used to meet the power factor requirements of any system, as it is capable of high power factor performance and low losses.

The working principle of the PFC713EG is based on the pulse-width modulation (PWM) control technology. It uses high-frequency switching of the input voltage to reduce the input power losses and improve the power factor. The PFC713EG’s PWM control algorithm is designed to regulate the input current waveform and minimize total harmonic distortion (THD) of the input current. It also provides good input voltage regulation and fast transient response, while reducing conducted EMI.

The PFC713EG has integrated protection features such as undervoltage lockout (UVLO), overvoltage protection (OVP), output short-circuit protection and maximum power limit (MPL). It also has an adjustable under-voltage protection (UVP), which can be configured through the external resistor. The PFC713EG is designed to meet the requirements of cULus and CE mark and is suitable for industrial, medical and commercial applications. It is RoHS compliant and rated for up to 70 degrees Celsius ambient temperature.

The PFC713EG is a cost-effective and high-performance power factor controller. It is an ideal choice for applications that require high power factor correction and high efficiency. With its protection features and wide operating temperature range, the PFC713EG is an ideal solution for various industrial and commercial applications in need of reliable power factor correction.
