摘要

Compared with the traditional pulse-width modulation (PWM) or sinusoidal PWM voltage source inverters (VSIs), the proposed VSI with a proportional-integral current controller (PI VSI) offers superiority. It includes instantaneous current control and wave shaping, a fixed inverter switching frequency independent of the output frequency resulting in only known harmonics, and free-running carrier operation. An approach to modeling the proposed PI VSI is introduced, an example of the VSI power circuitry design is presented, and the PI controller design is discussed. Finally, the VSI load current is verified for harmonic contents and instantaneous current control capabilities, under normal, unbalanced, load outage and load short-circuit conditions.
