“…This work addresses the tree-like two-dimensional TL structure in Section II. Comparing this tree-like network system with comb-like network systems, which have been proposed in [6][7][8], the comb-like systems are found to be difficult in construction and maintenance because sources inside the system have different voltage, current, and power ratings and have different power factors. This newly presented tree-like network is a much improved system over the comb-like networks and the conventional series-parallel combined dc networks.…”

The generalized tree-like transmission line network system having n layers in total with m-to-1 branch connection at each joint (T-TLNS-n-m) is proposed to replace the traditional series-parallel combined dc networks to automatically accumulate identically distributed power cells into the large amount of useful power for the spacecrafts. The proposed system has the attractive features of simple structure, easy construction and maintenance, and low cost, because two kinds of parts, ac current sources and m-to-1 transmission line (TL) branch connection parts, are used in the whole system. A method of implementing ac current cells having high output impedance is proposed to improve the power collection efficiency of the whole network system. Simulated results show that that low-pass nominal ¼-or T-circuit with high characteristic impedance, which is used for the voltage source to current source converter in the current cell, improves the efficiency of the voltage inverter, filters out the harmonics, and increases the output impedance of the whole current cell.
