Multiphase multi-inverter drive with discontinuous synchronized modulation
TLDR
Simulations give the behaviour of six-phase systems with discontinuous synchronized modulation, including combined schemes of discontinuous PWM, which allow continuous phase voltages synchronization during the whole control range.Abstract:
Algorithms of discontinuous synchronized pulsewidth modulation (PWM), including combined schemes of discontinuous PWM, have been applied for synchronous control of four inverters feeding six-phase drive on the base of asymmetrical induction motor which has two sets of windings spatially shifted by 30 electrical degrees. The proposed schemes of synchronized PWM allow continuous phase voltages synchronization during the whole control range. Simulations give a behaviour of six-phase systems with discontinuous synchronized modulation.read more
