DSP Control of Three-Phase UPS Inverter with Output Voltage Harmonic Compensator
3상 UPS 인버터의 출력전압 왜형률 개선을 위한 고조파 보상기법의 DSP 제어
Abstract
This paper presents real time digital signal processor(DSP) control of UPS system feeding processor(DSP) control of UPS system feeding nonlinear loads to provide sinusoidal inverter output voltage. The control scheme is composed of an rms voltage compensator, the load current harmonics feed-forward loop for the cancellation of output voltage harmonics, and the output voltage harmonics feedback loop for system stability. The controller employs a Texas Instruments TMS320C40GFL50 DSP.
