Abstract

The low-frequency output noise that is caused by introducing random-switching control into DC-to-DC converters with output regulation, is discussed quantitatively. A modified converter model involving the unintended effect of random switching is derived from the consideration of noise-generation mechanism. After the theoretical analysis based on the model, it is clarified that the magnitude of output noise is in proportion to the variance of switching interval. The experimental results of a buck-type converter are compared with those obtained theoretically, so that the validity of the theoretical results is confirmed experimentally.
