Fuzzy Logic Controller Improves DC-DC Converter Efficiency
New control methods significantly reduce settling times and voltage regulation errors in power conversion systems.
Updated on Oct. 25, 2026 in Energy
Researchers have developed a fuzzy logic-based controller for single-input dual-output DC-DC converters. The system demonstrates superior performance in stabilizing voltage compared to traditional proportional-integral controllers.
Why it matters
Efficient power conversion is essential for modern electronics, and this new control method provides more precise energy management for multiple output requirements. This improvement helps maintain system stability under varying load conditions.
The fuzzy logic controller reduced 24V output settling time to 3.24 ms with 0.5% regulation error, compared to the proportional-integral controller's 5.83 ms time and 4.7% error. At 12V, the fuzzy logic system achieved 5.29 ms settling time.
