Improving Quick Response of Servo System Using Boost-Diverter with Regenerating Energy

회생에너지의 부스트인버터 구동방식을 적용한 서보시스템의 응답특성 향상

The regenerating energy of the servo system is mostly consumed as heats through the regenerating resistors. For the response of the servo system to be more improved, the paper proposes the boost inverter using the regenerating energy, The proposed boost inverter has the additional capacitor installed on the DC-link circuit for charging the regenerating energy from the load. To get the better response of the servo system, the charged regenerating energy can be shortly re-applied to the output side as the finite impulse voltage, which can be controlled from information of reference voltages and feedbacked currents. It is verified by PSIM simulator that the response characteristics of the servo system using the proposed boost inventer is improved, comparing to that using the general inverter.
