Abstract :
Trapezoidal voltages can be used to compensate for the inverter nonlinearity. Especially, the modulating shape of those voltages facilitates adaptations to varying operating conditions. In this paper, practical schemes were proposed to improve the performance of the compensation method using the trapezoidal voltages. After those schemes are detailed, their effectiveness is confirmed through experimental results.
