Naturally sampled triangle carrier PWM bandwidth limit and output spectrum

  title={Naturally sampled triangle carrier PWM bandwidth limit and output spectrum},
  author={Isabel Deslauriers and Nysret Z. Avdiu and Boon Teck Ooi},
  journal={IEEE Transactions on Power Electronics},
This paper first presents a general theory predicting harmonic components in naturally sampled pulse-width modulation (PWM) output signals, so that any input signal with a Fourier series representation may be handled. This theory provides a basis for the mathematical analysis of PWM systems, such as converters transmitting a main signal and a broadband of feedback or feedforward signals, or Class D amplifiers. Ultimately, the results of this theory are applied to two concrete problems, and… CONTINUE READING
