A Simple Carrier-Based Modulation for the SVM of the Matrix Converter [PDF]
, 2013 Today, industry has not fully embraced the matrix converter solution. One important reason is its high control complexity. It is therefore relevant to propose a simpler but efficient modulation scheme, similar as three phase voltage source inverter ...

Comparison of single- and double-sided pulse width modulated signals with non-linear predistortion
, 2012 Class D amplifiers are based on a low-bit pulse width modulated (PWM) signal reconstructed through the lowpass characteristic of the loudspeaker. To create a PWM signal, a non-linear conversion from a standard pulse code modulated (PCM) signal has to be ...
