Pulse Width Modulation’s Impact

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 Modulated Rectifiers [PDF]

, 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 ...

Accelerometer with pulse width modulation

The Journal of the Acoustical Society of America, 1992
An accelerometer having a movable electrode which is moved according to acceleration with respect to a fixed electrode disposed in opposition to the movable electrode. An output device generates an output voltage which is proportional to the acceleration by measuring a gap between the movable electrode and the fixed electrode.

Improvement of pulse width modulation techniques

Archiv f�r Elektrotechnik, 1975
Pulse width modulation (P.W.M.) techniques, adopted in inverters for modern variable speed drives, allow an easy adjustment of the fundamental component of the output voltage.
