The paper presents novel strategy of synchronous control of five-phase inverters in the zone of overmodulation. New time-domain-based approach for analysis and synthesis of algorithms of synchronized pulsewidth modulation (PWM) allows providing smooth three-stage transition from a linear modulation region to the ten-step control mode of five-phase systems with space-vector modulation. Simulations...
The paper presents results of analysis of operation of asymmetrical split-phase (six-phase) electric vehicle drive on the base of two neutral-clamped converters, controlled by combined schemes of synchronized pulsewidth modulation (PWM), providing both common-mode voltage cancellation and continuous synchronization of the output voltage of inverters during the whole control diapason. Simulations give...
The paper presents results of dissemination of a novel method of synchronized pulsewidth modulation (PWM) for control of dual (cascaded) neutral-point-clamped inverters for photovoltaic generation. Basic system topology includes two insulated strings of photovoltaic panels, feeding two cascaded neutral-clamped inverters, connected to grid by a three-phase transformer with the open winding configuration...
New method of synchronized pulsewidth modulation (PWM) has been disseminated for control of dual neutral-point-clamped inverters feeding asymmetrical dual three-phase (six-phase) motor drive with two DC voltage sources. A novel control strategy for this drive topology is based on variation of switching frequencies of each inverter depending on the magnitudes of voltages of the corresponding DC sources...
This paper presents results of application of algorithms of synchronized pulsewidth modulation (PWM) for control of hybrid electric vehicle drive supplied by dual three-phase inverter system with two DC sources. Both standard linear V/F=const and non-standard non-linear control regimes of hybrid vehicle drive with synchronized PWM have been analyzed and compared. Simulation results are given for the...
This paper presents results of application of a new method of synchronized pulsewidth modulation (PWM) for control of symmetrical six-phase traction drives with two DC sources. The six-phase (dual three-phase) drive system includes in this case a symmetrical induction motor which has two sets of windings spatially shifted by 60 electrical degrees. Analysis of operation of the symmetrical six-phase...
