Key Points

To develop and evaluate random modulation techniques that maintain a constant switching frequency in three-phase power conversion systems.
Designed random pulse-width modulation algorithms constrained to a fixed switching cycle.
Evaluated the spectral characteristics and conversion behavior in three-phase power converter topologies.
Distributed discrete harmonic energy into a continuous, lower-amplitude spectral floor.
Preserved predictable switching cycles across power converter phases while dampening acoustic and electrical noise spikes.
