Description: Abstract: Randomized modulation is of increasing interest in power
electronics and also holds promise for reducing filtering requirements
in ac/ac, dc/dc converter application and reducing acoustic noise in
motor drive applications. This paper deals with the power spectrum
density (PSD) estimation methods of the random controlled pulse
width modulation (RPWM) single-phase structured boost rectifier.
Estimated PSD is also experimentally verified. The switch-mode
operation of the converter results in Electromagnetic Interference
(EMI) which is produced due to large di/dt and dv/dt. In addition to
all steps to minimize the generation of EM1 (i.e. introduction of
RPWM), improvement of power spectra will also be considered.
