Spectral Analysis of Square-wave Pulse Density Modulation: An Analytical Approach
نویسندگان
چکیده
The pulse density modulation technique has been used in resonant power converters because its ability to maintains soft-switching for any level of output power. The sub harmonics of the switching frequency are in general undesired and are seen as a drawback. In this work are developed analytical equations to express the harmonics and sub harmonics components of a PDM signal. It is still analyzed the PDM parameters variation and their effects in the frequency spectra.

Spectral Analysis of Pulse-Modulated rf Signals
The parameters that characterize a rectangular-shaped pulse-modulated sinusoidal signal are the carrier frequency, the pulsewidth, the repetition frequency, and the number of pulses in or the duration of the signal. We use a Fourier series representation to show the influence of these parameters on the spectrum of a pulse-modulated signal at a microwave carrier frequency. When an additional amp...

Abstract: As the size and the cost of power semiconductor switches are decreasing, converter topologies with high device count are starting to draw more attention. One such type of converters is the high frequency AC (hfac) link converters. A popular control method for these converters is Pulse Density Modulation (PDM). The hfac link voltage of the converter in this paper is a high frequency, t...
