Abstract |
A DC power system has many loads with varied functions. Also, there may be large pulsed loads with short duty ratios which can affect the normal operation of other loads. In this paper, Voltage Bus Conditioner(VBC) without any current sensors 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 practicalty of the approach. |
