Abstract
A high-speed, microprocessor-based pulse width modulator for three-phase inverters, realizing the so called incremental pulse width modulation algorithm, is presented. Computational simplicity of the algorithm results in fast, on-line operating capability and low memory requirements of the modulator. Fast operation of the modulator ensures high effectiveness of low-order harmonic reduction of the inverter output voltage. Principles of the incremental pulse width modulation are explained and experimental results are provided along with the description of the modulator.
