Abstract
Coupled inductor scheme with a balancing winding is proposed in multi-phase voltage regulator (VR) application. Mathematic model has established for deep theoretical analysis. With the model, the tradeoff between the performance of efficiency and transient response is clearly revealed with different coupling coefficients. The model and conclusions have been verified by circuit simulation and tests.
