Pulse-Width Modulation of Z-Source Inverters
, 2005 Z-Source inverters have recently been proposed as an alternative power conversion concept as they have both voltage buck and boost capabilities. These inverters use a unique impedance network, coupled between the power source and converter circuit, to ...

Wireline equalization using pulse-width modulation [PDF]
IEEE Custom Integrated Circuits Conference 2006, 2006 Abstract-High-speed data links over copper cables can be effectively equalized using pulse-width modulation (PWM) pre-emphasis. This provides an alternative to the usual 2-tap FIR filters. The use of PWM pre-emphasis allows a channel loss at the Nyquist frequency of ~30dB, compared to ~20dB for a 2-tap symbol-spaced FIR filter. The use of PWM fits well
