Abstract:In this paper, two dual random space vector pulse-width modulation (RSVPWM) methods, Random Switching Period-Random Zero Vector Timing SVPWM (RSP-RZVT-SVPWM) and Variable Daley-Random Zero Vector Timing SVPWM (VD-RZVT-SVPWM), are proposed to apply in five-phase inverters. The proposed RSVPWM methods can decrease the amplitudes of high harmonics and spread harmonics concentrated around switching frequency and its integer times to a wider frequency band. The dual RSVPWM has a more continuous and uniform power spectrum which will alleviate acoustic noise and restrain electromagnetic interference (EMI) of the system effectively. In this paper, a series of simulation results are provided to verify the effectiveness of the two dual RSVPWM methods for five-phase inverter.
