Description
This paper uses the averaged switch modeling method to derive the small-signal model of multi-inductor hybrid (MIH) converters. While modeling complementary switches with DC-coupled transformers is enough for conventional converters, the models for the hybrid converters need additional modifications to reflect the actual converter behavior accurately. To demonstrate the modeling and analysis technique, the generated models of four example MIH converters successfully capture the higher-order transfer function characteristics by their higher number of inductors and capacitors. The result provides corroborated analytical proof that MIH converters behave similarly to the multi-phase Buck converters, while the flying capacitors contribute to pole-zero doublets that create minimal impact on the converter operation.
