Abstract
A novel method of direct synchronous pulse-width
modulation (PWM) is disseminated to three-level voltage source inverters with
control algorithms with elimination of the common-mode voltages in three-phase
drive systems with PWM. It provides smooth pulses-ratio changing and a
quarter-wave symmetry of the voltage waveforms during the whole control range
including overmodulation. Continuous, discontinuous and "direct-direct" schemes
of synchronous PWM with both algebraic and trigonometric control functions have
been analysed and compared. Simulations give the behaviour of the proposed
methods and show some advantages of synchronous PWM in comparison with
asynchronous at low ratios between the switching frequency and fundamental
frequency.
