摘要：

It is shown how leading-edge modulation can shift the undesirable right-half-plane (positive) zero of boost and flyback converters into the left-half-plane. This allows a substantial improvement in the closed-loop characteristics by yielding a minimum phase system. Several techniques are employed to predict this result. The design procedure for shifting the positive zero into the left-half-plane is presented. Experimental verification is provided.
