The design of modern power supplies should take into account changes in environmental and efficiency requirements. An important focal point for power supply designers is optimizing the Power Factor Correction (PFC) control scheme coupled to the EMI filter that can consume 5% to 8% of the output power at low line, full load.

When designing power supplies to optimize power savings, you need to consider the whole load range encountered in typical real-life operating conditions including full-, medium-, and light-load efficiency ratios. Read on to learn more about how PFC control scheme options help optimize efficiency and reduce cost over the whole load range.
