| Abstract |
The concept of a new pulse-width modulation (RPWM) scheme and weighted RPWM (WRPWM) scheme has been explored and put to test. Both schemes have been developed based on the very idea that harmonic energy at distinct frequencies can be spread out by randomizing the switching pattern. The formulation and analysis of RPWM / WRPWM schemes depends on the notion of randomness. However in practice we only use so called "pseudo-random" sequences generated by computers and/or circuits for implementation of these schemes. In this paper we discuss the effect of such pseudo-random sequences on the performance of RPWM / WRPWM schemes. |
