Abstract

Pseudorandom carrier scheme is a distinct approach for analysis of various demerits (Discrete frequency harmonics, Electromagnetic interference, audible switching noise etc.) occurring due to the switching frequency of a semiconductor device (MOSFET, IGBT etc.) in Power electronic system (PES). In the proposed scheme random synthesis of two triangular carrier waves opposite in phase are randomly selected by using 12 bit PN-Sequence generator on the basis of "0" and "1" bits of a 12-bit sequence (called as Pseudorandom binary (PBRS) sequence random bits). Train of switching pluses are generated using Pseudorandom carrier and a reference signal to control the BOOST converter output levels.
