Power Supply Design Seminar (PSDS) series. Webinar by Texas Instruments “Power Factor Correction (PFC) circuit basics”

06/09/2025

Since its introduction in 1977, the Power Supply Design Seminar (PSDS) series has provided rich, technical and practical training combining new advanced power supply concepts, basic design principles and "real-world" application examples. Whether this seminar is used to gain fresh knowledge of power management, or as a review for those experienced in power supply design, the topics presented will be worthwhile for all levels of expertise.

From laptop adapters to power tools, any application powered from the AC grid represents a complex load where the input current is not always in phase with the instantaneous line voltage. As such, the application consumes both real power as well as reactive power from the grid. The ratio between real, usable power (measured in watts) and the total real-plus-reactive power is known as the power factor. A power factor correction (PFC) circuit intentionally shapes the input current to be in phase with the instantaneous line voltage and inimizes the total apparent power consumed. While this is advantageous to utility companies, a PFC circuit also provides benefits in end applications. This topic presents these benefits, how the PFC circuit can impact the AC-to-DC power-conversion architecture, common PFC circuit types, the benefits/disadvantages of different approaches and a PFC solution selection process based on application priorities.

The seminar will be held on June 25, 2025.
