Transmitter pre-emphasis techniques to overcome high-slope losses of printed circuit board (PCB) with closely-spaced copper interconnect are presented. The pre-emphasis technique based on pulse-width modulation (PWM) using a timing resolution instead of an amplitude resolution to adjust the filter transfer function is presented.

Advanced Double Discontinuous Pulse Width Modulated Three-Phase Power Converter
2025 IEEE Energy Conversion Congress & Exposition Asia (ECCE-Asia)Three-phase bi-directional ac-dc converters are required to have high efficiency. To improve efficiency, it is required to decrease the number of switching transition. Therefore, a novel switching or pulse width modulation (PWM) strategy is proposed in this paper, where two phases are not switching in a switching period. To achieve this, an extra diode

Discontinuous modulation of the modular multilevel converter can be used for reduction of submodule capacitor voltages and switching losses by clamping one of the arms to its corresponding dc-rail. In this paper, the impact of discontinuous modulation in the losses as well as the expected thermal performance of the devices in the submodules of the ...
