摘要
Subharmonic oscillations exist in digital-average-current-controlled switching dc-dc converters with trailing-and leading-edge modulations. To eliminate these subharmonic oscillations, a digital-triangle-compensation (DTC) method is proposed in this letter. The DTC method can easily be implemented in digital way without an extra compensation circuit. Experimental results are given to verify the analysis results.
