Abstract :
A typical 2-level pulse-width modulation scheme for a DC-DC converter generates a signal that has two values, that is zero and one. For a random aperiodic scheme, the switching period can be modulated in a random fashion with a known probability density function. In this paper, analytical expressions for both discrete and continuous spectrum are provided for the case where different probability density functions are used to modulate the switching signal of a DC-DC converter. Experimental results are presented to support the theoretical claims.
