研究目的
To analyze resonant LCL-T converter in DAB configuration as voltage source mode being fed by PV battery operating in current source mode.
研究成果
The resonant LCL-T converter has the intrinsic ability to convert a current source into a voltage source, making it suitable for spacecraft power supply units where the primary source is a PV battery. The use of an active rectifier allows for high accuracy of parametric stabilization of the output voltage, from idle up to full load, without the need for frequency adjustment, simplifying control efforts.
研究不足
The study acknowledges the instability of PV battery output current level due to external conditions like illumination change and efficiency degradation. The phase shift control method, while effective, requires careful management to maintain the necessary conditions for soft switching and output voltage stabilization.
