COMMON MODE VOLTAGE ELIMINATION IN THREE-PHASE FOUR-LEG INVERTERS UTILIZING PULSE DENSITY MODULATION
… inverters by eliminating CM EMI using pulse density modulation (PDM) in conjunction with model predictive control (MPC) and delta modulation. A physics-based model of the equipment under test (EUT), utilizing state-space modeling, was analyzed using computer simulations and a laboratory …

A Distortion Suppression Technique for a Digital Class D Audio Power Amplifier with Pulse Density Modulation
… switching output node and the power supplies. Pulse Width Modulation (PWM) can provide over 100 dB THD at a switching rate well below 1 MHz, but can generate large EMI spikes at the switching frequency and harmonics. Many techniques have been developed to reduce this problem, such as spread …

Fully Soft-Switching Modulation Methods for SRC-Unfolding Inverter
… pseudo-dc-link inverters are based on pulse-width-modulated converters, which suffer from hard switching, the need for auxiliary components, and/or high current stresses. Meanwhile, the series resonant converter has been prevalent in past decades due to its simplicity and high …
