4 nefaileA Deacription of the Tnventio Ej EhboAi menf--: an AC power network with linear structure.
Please refer to FIG. 1, which is the first preferred embodiment of an AC power network of the invention. The AC power network of the embodiment includes a plurality of AC current sources with the same frequency, a plurality of quarter-wavelength transmission lines with the same characteristic inpedance, a'r'esi-stant load, and a resistant target load. It is noted that a AC current source can be characterized by a AC current phasor I with a magnitude A and a phase 0 denoted as 1 =A - eJO where AL,:O is a real number and j represents - Each pair of quarter -wavelength transmission lines has the same characteristic iripedance A) and induces 900 phase delay between both AC phasors respectively connected to its both ends. The AC current sources are linearly connected by the quarter-wavelength transmission lines. Inside the dashed-line rectangular of FIG. 1, the two AC current phasors with the same magnitude and 90 degree phase difference are called a pair of AC current sources. The magnitude of the kth pair of AC current source is denoted as Ak. The power network shown in FIG. 1 consists of n pairs of AC current sources linearly connected with quarter -wavelength transmission lines, a resistant load RZ.2, and a resistant target load RL2. Hence, the phasor of the kth AC current source can be written as 2 IS'k = (Ak_1 + A,) - e for k--1, 2 n+ 1, (1) with AO=A,,,,=O. According to the theories of transmission lines and superposition, the AC voltage phasor Vk and AC current phasor 1,,k of the kth port of the power network in FIG. 1 can be represented as Vk A, - ZO 21 (2) 1=0 1"k A, eit 2 1 i=O (3) In addition, the output power Ps,.t and the collected power P,,j, of the kth AC current source and the kth port are described as 1 (At PS'k = Vk - IS, k - ZO + Ak) - J:A (4) 2 2 i=O I - 1 Am. Ai = (5) P"k = Vk - ',,,t ZO 2: 2: 2: PSM 2 2.=O i=O M=1 where the denotes the complex conjugate operation. It is obvious that the output power efficiency of every AC current source is 1, the collected power at the resistant target load Rz.2 is maximnun, and the collected power at the resistant load Ra is zero. Second Embodi ment: an AC power network with tree structure.
According to the equation (5) of the first preferred embodiment, the AC current source near the resistant target 6 I load RL2 much more is needed to of f er higher output power. The AC current source near the resistant target load R,, ca.-n be replaced by another linear AC power network of the above embodiment. Hence, the second preferred errbdirne_nt- of t1h-e 5 invention shows an AC power network with a tree structure.
The second preferred embodiment of an AC power network of the invention includes a plurality of AC power calls witth the sarne frequency and phasor connect-ad by a plural J ty of 1 - J (Tuar ter -wave'L encrth transmission lines with the same characteristic irmedance.. and a resistant target load. In the case.. t"!,.e power cells are current sources. Each pair of quarter -wavelength transmission lines has the same characteristic impedance ZO and induces 90 degree phase delay between the two AC current sources connected to its both 1 ends. The AC power network constructs a tree structure with_ a r c. o' iC a r. --ft a - P u - r a _1 t o f 'A Dranches andnodes. T..
Y h e r a s _J s t an."t tarcret load is the root, a pair of quarter-wa.relength t_-ansmission lines forms a branch, and AC current sources are t1he ending nodes The ending nodes of the AC power 2 0 network is the 'Leaves of the tree structure, and they a-re a,oart from --'.,.a root with the same number of branches. Th.c nodes excludincr the ending nodes denote the I ocattions o3 le- _L L -t-ng branches.The nodes with the same nmTher o-f branches away from the root form a class. The ending node.-S 225 f orms, the class one (CI) The nodes in the sarryie class col-lect 7 the same number of branches. FIG. 2 shows an AC power network with four- class tree structure- A dashed contour denotes one class, and the leaves of the tree forms the class one (Cl). The nodes with one branch away from the ending nodes forms the class two (C2). Similarly, the classes three (C3) and four (C4) are formed. In FIG. 2, the resistant target load forms C4. The nodes of C2, C3 and C4 collect the same number of branches.
Let the phasor I of each AC current source be I = 1 - e jo and the characteristic impedance of each pair of quarter -wavelength transmission lines is ZO=500. It Is clear that the AC power network with tree structure of this embodiment can be seen as an assembly of AC power networks of the first embodiment. Hence, according to the result of the AC power network with linear structure shown in the first embodiment, the maximum collected power of the network locates at the resistant target load. FIG. 3, A, and 5 show the simulation results of the tree- structure AC power network with different values RL=250 (RL<ZO), &=500 (&=Zo), and &= 10 0 Q (RL>Zo) of the resistant target load, respectively. It is clearly obtained that the more higher power is collected at the port more near the resistant target loadl and the maximum power is collected at the resistant target load.
In FIG. 2, the nodes excluding the ending nodes collect 8 three branches. FIG. 6a shows another case of the embodiment, which the numbers of branches collected by the nodes of different classes are different. It is noted that the result of the case in FIG. 6a is same as the case in F1Gx_ 2- FIG,- Gb shows the real connection of the branches and nodes in the dashed-line contour PC shown in FIG. 6a. Inthecases of FIG. 2 and 6a., the AC power cells are AC current sources. FIG. 7a shows a further case of the embodiment, whose AC power cells are AC voltage sources.. and the pract.JLcal in.plement of the branches and nodes in the dashed-line contour PC of FIG. 7a are shown in FIG. 7b.
Third Embodiment: an AC power network with tree structure and global equal potential rings.
Please refer to FIG. 8a, which shows a network with two AC current sources, two resistant loads, and three bran-ches. Both branches respectively between the A-, current source with phasor Is, and the resistant load R, and -between the AC current source wi t1h., phasor 1,,, andl t"ble resistant load R, are two pairs of quarter-wavelenath transmission lines with impedance Zo, and the branch bet--7een both -kC current sources is a pair of k-wavelle-n-gf-J-h- 4..
transmission lines with impedance ZO and k-I. A pair of k-wavelength transmission lines with Airrpedance w_111 cause kx360" phase delay between both AC phasors respective1y t b-t-k to 4-1-a 2_5 connecz'_-ed t--_ onds. AccordJng 9 transmission -line theory, the AC voltage phasors Vj,j and V2,1 of both AC current sources Is, and IS2 are equal, i. e., V1, =V2, 1. In addition, it is obtained that 11,2=12,2. However, the AC current phasors I,,, and 12,1 may not be equal, and so do the AC voltage phasors V1,2 and V2,2. Since the AC voltage phasors at both ends of the, pair of k-wavelength transmission lines as shown in FIG. 8a are equal, the pair of k-wavelength transmission lines is callea an equal potential ring.
Please refer to FIG. 8b, which shows a network with two AC current sources, two resistant loads, and four branches. Both branches respectively between the AC current source with phasor Is, and the resistant load R, and between the AC current source with phasor IS2 and the resistant load R2 are two pairs of quarter -wavelength transmission lines with impedance ZO, and both branches respectively between both AC current sources is, and IS2 and between both resistant load R, and R2 is a pair of k-wavelength transmission lines with impedance ZO and k--1. According to the transmi ssion -line theory, the AC voltage phasors V1,1 and V2,1 of both AC current sources Is, and IS2 are equal, i.e., Vl,,=V2,1, and so do the AC voltage phasors V1,2 and V2,2 of both resistant loads R, and R2, i.e., Vl,2=V2,2- Consequently, it is obtained that 11,1=-T2,1 and 11,2=12,2- It is noted that, with the equal potential rings, all AC voltage phasors between each equal potential ring are equal, and so do all AC current phasors between each equal potential ring.
Please refer to FIG. 9, which is an _kC power network with three-class tree structure, which includes nine AC current sources at Class 1 (C11/. The dashed contour at the class 1 (Cl) denotes the closed contour (r1l) of equal potential rings, which connect all the AC' current sources. There are three branches at each note of the AC powernetwork. In addit-.ion, three of the nine AC current sources havem larger AC current outputs than others'. Hence, the power d-Lstribution of the JALC network is heavily non-un-if o=. From 4--.Ne S j - I a4- 'on -results of the AC network shown -;__n FIG. 9, _M%2_L C.:_ because there are equal potential rings at class 1, the voltages of the nodes at class 1 are equivalent; however., they are d1f f erent at class 2 Besides, in FIG. 10, the equall potential rings connect all the nodes at classes 1, and so do at class 2. it is very clear that all the voltages and curren,'s of the nodes at class 1 are eTuivalent. so ein tlth- nodes at c.1ass 2. This means that the power dist-rx-bui-Loii 4-he A,- network is equalized at each class by Ji-riserting 0 equal pot-en4-; al rJ ngs. In addition, the collected po-V-1-=-.r 01ME the res-istant. target load is -maximmm.
AccorcLj-ng to the above result, three--asesof theth--l-rd en-bod_-Lment of the invention are shown -Lin FIG. 1!, 12 and 13.. respectively. The first case as shown an FIG. 11 is an AC pov.,er net,,-,-o_rk -.-.,ith f live-class t-rac Structure. AC current 11 sources., and ecruai potentiai rings connecting all nodes of each class (C1, C2, C3, and CA). Every branch of the tree structure consists of a pair of quarter-wavelength transmission 11-JI-nes. number of branches of the nodes at the class with equal potential rings are not needed to be equal. Since all power cells of the AC network are AC current sources, the first case of the third enbodiment is called an current--type AC iDower network with tree structure and global equal potential rings. Please refer to FIG-- 12, wh-&Lch is t-IN-e second case of the third embodiment- Tbe on.1v -z-',Pe-ence of the firs' and second cases 4s that the AC L. - -- LA current source of the first case are replaced with an AC voltage source and a pair of quarter -wavelength transmission lines. The second case is called an voltage-type AC power network with tree structure and global equal potential rings. D. =ddJ" on. FIG. 13, the third case -f 1-7%e s sho-Nm Dhe power cells -f the c;.i.se consi-st of the AC current source, and the AC voltage source witi.1 a pc-L-;Lr of quax ter -wavelength transmission 1-;;_P.es. is called an hybr.-Ld-type AC power network with tree st-ruct-urq and global ecfaa.1 potential rings_ Tt J s very J ortant that the equa-I L -LIITP - - -- LA 1.

12 orth En-bodimen: an AC power network with tree structure and local equal potential rings.
In the third errbodiment, all classes without the resistant target load have equal potential r-Lngs, a.-Lid t.1-le equal potential rings at each class foxTrL one contour. Tr the forth errbodiment, there is at least one contour of equal potent rings at the same class. In FIG. 14, the forth embodizmnt of the invention, an AC power network with f our-class tree structure and loca'L equal potential rings.
is- shown. The AC power network includes a plurality of AC power sources, a resist-ant target load, and atree struct-ure with branches and nodes. The branches are constructed by quarter -wavelength transmission lines. Nodes at each class are not needed to possess the sarm number of branches, for example: in the class 2, there are two branches at the node Af the-re are four branches at- 'the node E, and t-here are tw,--, branches at the node C in the class 3- The ending nodes:
i.e. thle nodes in the class 1, are the AC current sources whose phasors may have different magnitudes. In the sarne class (say class k), these nodes connected to t-he same node in its preced-ing class (say class k+!-,l construct a group of nodes. In the odd classes of this embodiment o the invention, such as c1ass I and class 3 etc., every group of nodes has one local contour of equalL potential, rinqs connecting all its nodes. For exaxrpie, th.e PC current- 13 sources of this embodiment shown in FIG. 14 construct eight groups in class 1, and there is a contour of equal -potential rings connecting the nodes of every group. In addition, in class 3,. there is only one group of nodes.. there is only one 'Local contour of equal potential rings. In class 2 there is no equal potential ring.
Every local contour of equal potential rings, in class I are used to eaualize the output powers of the AC current sources in the same- group of nodes, which the phaso-rs of these AC current sources may have different magnitudes. The local contour of equal potentiall rings, in class 3. are used to make the power distribution of the AC power network uni.f ormly. In addition, the collected power of the resistant tarqet load --L;s maximurrL. This embodiment of the invention is called an AC power network with tree structure and equal iDotential ri n-s.
Please ref er to FIG. 15a and 15b, which are two eabbodim.ents of a qna, ar ter -wave length transmiss-ic-In. 11i.ne im,edance- Zn. The first. one shown in FIG. 15a is 't-he lunp n-circuit which consists of an inductor with inductance and two capacitors with capacitance I/ (co-Zo) where (o is 'the AC pover cells I frequency.

Fifth Embodiment: an AC power network with multi-plane structure and equal potential planes.
I ri Acco-rd-ing to the above results of cLifferent equal potential rings, two cases of the fifth embodiment of the invention are shown in FIG. 16a and 16b. In FIG. 16a, the first case includes at least one resistant target load, a plurality of AC power cells, a plural pairs of quarter15', wavelength transm.ssion lines, and a pluralit-y of ecrac-A-1 votentic-a-1 rinas. The equal potential rings consik-.ruct chess-like equal potential planes whose node's number is not less than the number of the AC power cells. One AC power cell is connected to one node of the f ist chess -like ecra potential plane. Both corresponding nodes of successive chess-like equal potential planes are connected by a pa3-r of quarter-wavelength transmission lines. The resistant target load is connected to one node of the last chesslike ecfual potent.-L;ai plane.
