Abstract
In this paper a 3-fold interleaved inverter used as power amplifier is examined. First, a comparison between the classical multilevel topology and interleaved topology in a fullbridge configuration is made. After that, a generalized PWM modulator for multicell topologies will be defined. Lastly, a simple method is proposed to suppress harmonic distortion caused by tolerances in the cell inductors. Within this method the phaseshift will be recalculated, based on inductance values, in such way that the fundamental switching frequency component is removed from the spectrum. An analytic and a graphic method, supported by simulation results, to calculate the phase-shift is presented.
Finally, results from an experimental setup are shown to verify the proposed ideas.
