A novel current-driven synchronous rectifier is presented in this paper. With the help of current sensing energy recovery circuit, the proposed current-driven synchronous rectifier can operate at high switching frequency with high efficiency. Compared with those voltage-driven synchronous rectification solutions, this current-driven synchronous rectifier has several outstanding characteristics. It can be easily applied to most switching topologies like an ideal diode. Constant gate drive voltage can be obtained regardless of line and load fluctuation. This makes it desirable in high input range application. Converters designed with this synchronous rectifier are also capable of being connected in parallel without taking the risk of reverse power sinking. Principle of operation is given in the paper. A series of experiments verify the analysis and demonstrate the merits.

This paper introduces the Component based architecture (CBA) employed in a software to design the switching mode power supply (SMPS). Theoretically, there is a unique mapping between a real converter and its behavior. Based on a known circuit topology, the proper design is underlining in the combination of components and its physical configuration. Neither abstract electrical model nor domain knowledge is expected from the user. Besides, this architecture turns optimizing the abstract parameters into component selection.
