Abstract:
In dc microgrid systems, bus impedance, filters, and converters can cause input voltage and current oscillations in power converters with input filters. This paper introduces an oscillation-resistant solid-state single-port series damper (S 3 damper).
A transistor acts as an ac resistor to form the damper between the input filter and the converter. It lowers the filter quality factor and dampens the converter-filter interaction. To prevent bus voltage and current oscillation, it raises the filter’s input impedance. To save power, the transistor is regulated at a low dropout voltage. Autonomous control.
The damper has no power capacitor or inductor, making it compact and reliable. The S 3 damper will be modeled, designed, and analyzed. A prototype damper for a commercial 100 W 48 V dc-dc converter has been built and tested.
