The Introduction Of PMIC-PFC (Power Factor Correction)

PMIC-PFC (Power Factor Correction) is a power management integrated circuit (PMIC) that is used to improve the power factor of a circuit by controlling the input current of the power supply.

Power factor correction is an important factor for ensuring power systems work at their optimal levels and meet safety requirements. A power factor correction circuit is often included in power supplies, and sometimes in other equipment, to make sure power delivery is efficient and reliable.

The TEA1532CT/N1,118 is a high-power PFC controller chip that integrates the power factor correction function into an integrated circuit. It is designed to ensure an efficient and reliable system performance. The chip can provide power factor correction with up to 1.18 (at 115 Vrms, 50 Hz). It is also capable of supporting advanced algorithms and innovative designs which can up the power factor to up to 1.38.

Working Principle Of TEA1532CT/N1,118

The TEA1532CT/N1,118 features a PFC controller IC with an integrated driver circuit. This IC works using a control algorithm which accurately controls the Switching devices to maintain an appropriate input current waveform and power factor correction levels over a specified load range. The controller utilizes an array of parameters such as the output voltage of the PFC, the input current and bus voltage, and pulse-width modulation (PWM) frequency to set the switching points and increase power factor accordingly. The chip also features an under voltage/over current lock-out (UVLO), an over temperature shutdown (OTSD), a maximum peak voltage (MVP) control, and a Sleep Mode.

At start-up, the PFC converters are enabled in a pre-defined order with the current limiter and the PeakVoltage limiter set. After the initial single-cycle conversion period, the chip continuously monitors and regulates the output voltage to maintain a higher power factor. The peak current is then monitored and the operating parameters adjusted to meet the load demands effectively.

The chip features several features which help with power factor correction. These features include: Current Sharing, which allows for shared current sharing amongst synchronized PFC converters and provides increased current capability. It also features Soft-Start, which allows the converter to smoothly transition to operation, which helps to prevent inrush current in the converter.

The Benefits Of Power Factor Correction

Power factor correction has many benefits that make it a valuable addition to any power system. By providing active power factor correction, the TEA1532CT/N1,118 chip can help to ensure a reliable and efficient delivery of power. The chip is designed to meet the most demanding requirements for an optimal power supply. Additionally, it features a range of features and settings which can help to maximize efficiency and minimize wastage. This helps to reduce operational costs and improve overall performance.

The chip also helps to reduce power line noise and harmonics, a common problem in many electrical systems due to the presence of resistive loads. When the power factor is regularized, the harmonics tend to drop significantly. By improving power quality and stability, power factor correction also helps to increase system reliability, reduce system malfunctions, and extend the service life of connected equipment.

Conclusion

The TEA1532CT/N1,118 PFC controller chip is designed to improve the power factor of a system by monitoring and controlling the input current. Thanks to its innovative design, the chip is capable of maintaining a power factor of up to 1.38 and provides several benefits such as improved reliability, better power quality, reduced noise and harmonics, and improved system efficiency. This makes it an effective solution for any application that requires an efficient and reliable power delivery.
