Digital Control allows PFC efficiency improvement at light load

ICERGi has implemented enhancements to its power factor correction (PFC) stages by refining its digital modulation algorithms, with a focus on maximizing efficiency under light-load conditions. These improvements ease the efficiency demands on downstream DC-DC conversion stages and contribute to better overall system performance.

• +1.84% efficiency gain at 100 W (high-line)
• +1.14% efficiency gain at 100 W (low-line)

The impact of these improvements is illustrated in the performance graphs.
