A Voltage Bus Conditioner with reduced capacitive storage

Distributed Power System (DPS) have many loads with varied functions. In particular, there may be large pulsed loads with short duty ratios which can affect the normal operation of other loads. In this paper, a converter with spilt capacitors and an adaptive controller is proposed as a Voltage Bus Conditioner (VBC) to mitigate the voltage transients on the bus. The proposed converter allows the smaller capacitive storage. In addition, the proposed control approach has the advantage of requiring only one sensor and performing both the functions of mitigating the voltage bus transients and maintaining the level of energy stored. Simulation results by Saber package are presented which verify the control principles and demonstrate the practicality of the approach.
