Abstract: In the control of voltage source inverters, automatic control systems became widespread. One of the representatives of such control systems is a hysteresis control which is based on a nonlinear feedback loop with hysteresis comparators. However, the application of voltage source inverter with hysteresis voltage control is not considered enough in foreign and Russian technical literature. These papers provide only the description of control algorithms, implementation methods, while many issues remain unresolved. This paper presents total current harmonic distortion and total voltage harmonic distortion of voltage source inverter with hysteresis voltage control depending on the load and output filter parameters. Weighted total harmonic distortion was considered too. Analytical equations for this coefficient are presented. Computations can be used to estimate the output energy quality of voltage source inverter with hysteresis voltage control.
