Abstract

Synchronous Delta-Modulation systems are used to control resonant voltage link inverters, where switching has to be synchronized with the zero crossings of the link voltage. This paper shows that output current harmonic distortion and average switching frequency of such systems can be calculated analytically in spite of the quasi stochastic behaviour of the modulator output. Under the assumption ofconstant link frequency and large ratio of link to output frequency, results are derivedfor three-phase Sigma-Delta-Modulation, space-vectorbased Sigma-Delta-Modulation and current regulated Delta-Modulation. The results hold for any shape of the inverter input voltage (including DC). The output current harmonic distortion of resonant link inverters is compared with conventional hard switching PWM inverters.
