Pulse-width modulation - Open Access .click

2021
PWM technologies have multiple impacts on the power electronics converters. First, the switching losses of power electronics devices will be accumulated together with PWM and impact the converter power losses. Second, pulse voltage will cause ripple on the passive components in the output side.

Principle of Pulse Width Modulation

2021
In Chap. 1, the basic concept of pulse width modulation has been introduced briefly. In this chapter, the principle of pulse width modulation will be further discussed. Based on fundamental principle, space vector PWM (SVPWM) and carrier-based PWM (CBPWM) will be presented, respectively, together with the relationship between these two approaches. With

Pulse-width modulation in sigma-delta modulators

Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010
Time-encoding machines map analog or multi-bit digital signals to a binary stream. The information contained in the input signal is preserved by the high resolution achieved in the time domain. Pulse-Width Modulators (PWMs) rely on a similar operation principle.

Pulse-Width Modulated Rectifiers

2001
To obtain low ac line current THD, the passive techniques described in the previous chapter rely on low-frequency transformers and/or reactive elements. The large size and weight of these elements are objectionable in many applications. This chapter covers active techniques that employ converters having switching frequencies much greater than the ac ...
