병렬 펄스 부하를 갖는 DC전력 시스템의 전압 안정화를 위한 Voltage Bus Conditioner의 전류 센서리스 제어

초록

A DC power system has many loads with various function. In this paper, Voltage Bus Conditioner(VBC) without any current sensor is proposed to damp the bus voltage transients by parallel pulsed loads. The proposed control approach requires only one voltage sensor and carries out both the functions of damping the bus voltage transients and maintaining the level of energy stored. The proposed control technique has been implemented on a TMS320F2812 Digital Signal Processor(DSP). Simulated results by a Matlab Simulink and experimental results are presented which verify the control principles and demonstrate the practicality of the approach.
