Parametric Analysis of Domains with Desired Dynamic Modes in Single-Phase Voltage Source Inverters

The results of parametric analysis in single-phase voltage source inverters with bipolar reversible sinusoidal pulse-width modulation are considered.The effect of quantization factor on the domain size with desired dynamic mode is studied. Research on the selected space of system parameters by variation of pulse-width modulation (PWM) quantization frequency with constant frequency of control voltage and conversely by variation of control voltage frequency with constant quantization frequency is carried out.It is shown that control voltage frequency variation with constant quantization frequency has virtually no effect on domain with desired dynamic mode. At the same time, increasing switching frequency, if it is technically possible, allows to completely eliminate undesired modes without using complex nonlinear dynamic processes control algorithms.Mechanism of quantization factor influence on domain with desired dynamic mode for systems with sinusoidal PWM is presented for the first time. The obtained results can be used in parametric synthesis of control systems in single-phase voltage source inverters based on various types of a sinusoidal PWM.
