Abstract :
There has been a continuous development of PWM strategies addressing different inverter topologies, as well as requirements of efficiency and minimal distortion. One of such strategies recently proposed by the authors is Feedback Quantizer PWM (FBQ-PWM). In this paper we briefly describe FBQ-PWM. We present a detailed study of different feedback filter options for noise spectrum shaping. We illustrate our study with detailed simulations and experimental results. The paper is concluded by a summary of its main findings and notes on potential applications.
