A new conrol scheme is developed o regulae boh oupus simulaneously. Compared wih discree configuraions, he proposed inegraed converer uilizes a lower number of swiches due o he reuse of componens. The converer characerisics are sudied comprehensively. I is demonsraed ha all MOSFETs are urned on a zero volage wih reduced swiching losses. For he sep-up sage, he converer provides a high boos raio and is able o clamp he swich volage spikes. For he sep-down sage, he seady-sae characerisics and he dynamic performances are similar o ha of he convenional buck converer. Moreover, he sep-down oupu por can be exended o muliple pors, where he single-inpu-muliple-oupu SIMO) version of converer can be derived. A 25 W, 42 o 39 and 15 converer prooype is designed, analyzed and esed. The experimenal resuls are presened o verify he feasibiliy of he opology. Keywords dc/dc converer; inegraed converer; single-inpudual-oupu SIDO); single-inpu-muliple-oupu; zero volage swiching. Single Inpu Single Inpu High Sep-up Converer Sep-down Converer a) Inegraed Dual Oupus Converer v o1 v o2 v o1 v o2 I. INTODUCTION Muliple oupus dc/dc converers are used in a wide variey of applicaions, such as LED drivers [1], [2], dc nanogrids [3] [5], porable devices [6], plug-in elecric vehicles [7], mulilevel inverers [8] and communicaion power supplies [9]. Among hem, SIMO dc/dc converers have heir advanage of reduced circui complexiy. Fig.1 a) shows a ypical sysem diagram wih wo discree power sages. While Fig. 1 b) shows an inegraed dual oupu sysem implemened wih a hree por converer. In comparison wih he discree version, he inegraed converer uilizes a lower number of swiches due o he reuse of componens. This leads o reduced swiching losses and he removal of he redundan componens. Meanwhile, many applicaions such as high inensiy discharge lamp ballas used in auomoive headlamps, call for high sep-up raio converers [1]. The main challenges lie in a) how o exend he sep-up raio; and b) how o alleviae he volage spikes across he swiching devices inroduced from he ransformer leakage inducor [11]. A flyback-boos derived converer is proposed in [11]. The proposed opology provides a high volage gain wihou incurring exreme duy raios. However, he opology is only explored in single-inpu-single-oupu scenarios. In [12], he b) Fig. 1. Schemaic of power converer archiecures wih dual dc oupus: a) discree version; b) inegraed version. concep of SIMO was repored. A class of SIMO converers have been inroduced in [13] [16]. In [13], [14], some highly efficien SIMO dc/dc converers were proposed. However, only one acive swich is employed. This makes i infeasible o regulae boh oupus simulaneously. A SIMO dc/dc converer wih reused swiches [15] was proposed. However, i can only provide sep-down oupus. This means ha i is no an opion for applicaions where sep-up oupu is required. A family of SIMO dc/dc opologies wih one sep-up and muliple sep-down oupus are proposed in [16]. However, he converer suffers from considerable swiching losses due o he hard swiching. This paper proposes a novel inegraed dual-oupu converer as showed in he Fig. 2), which can provide one high sep-up oupu and one sep-down oupu. The proposed opology enjoys he benefis of a) reduced swich coun compared wih is discree counerpars; b) zero volage swiching ZS) among This work is sponsored in par by Shanghai Sailing Program 16YF1476) /16/$ IEEE

II. POPOSED SIDO CONETE i i A. Topology Descripion The proposed converer origins from he convenional flyback converer. As shown in Fig. 2, a volage-doubler recifier nework is added on he secondary side of he flyback converer. Furhermore, a bidirecional boos converer is insered o form a parallel-inpu-series-oupu configuraion. Moreover, by adding swich Q 2 ) series wih Q 1 plus a LC ler nework, a sep-down oupu por is implemened. By acively conrolling he duy raios of Q 1-3, he converer provides a high sep-up oupu and a sep-down oupu simulaneously. The inermediae bidirecional boos srucure ensures he sof swiching of all he swiches. Furher advanages such as a) high swich working frequency, b) high device uilizaion rae, and c) swich volage sress clamping can also be achieved using he proposed opology. B. Operaion Principle The key seady sae waveforms of he proposed inegraed SIDO converer are ploed in Fig. 3. As shown, in each swiching cycle, here are nine differen operaing modes. The nex swiching cycle is symmerical o he firs swiching cycle. One specific swiching period, [, 9 ) is exraced for deail analysis. Those nine operaing modes correspond o nine equivalen circuis as ploed in Fig. 4. The operaing modes analysis is based on he assumpion ha C b, C 1, C o1 and C o2 are sufficienly large, such ha heir volage ripples can be ignored. Thus, hose capacior volages are considered as dc volages,,, Co1 and Co2, respecively. Mode I: [, 1 ). A -, he body diodes of Q 1 and Q 2 are conducing, which creaes a zero volage condiion for he urning on of he MOSFETs. A, he MOSFETs channels are urned on wih ZS. The volage across L m is cb co1 )/n.

Fig. 5 shows he corresponding curren waveforms under hose assumpions. According o he law of energy conservaion, by applying he principles of capacior charge balance on C b, and vol-second balance on L and L m, he sep-up raio of he converer, M 1, can be derived as, 1 n) 2 2) 1 2) o M1 = = 1+ i nl f s D D 9) where, f s is he swiching frequency, is he load resisance on he high volage oupu, and is he duy cycle of Q 2. When n equals o zero, M 1 coincides wih he sep-up raio of he classical boos converer. The sep-down raio of he converer is, 1 1 Co2 = = 1 D 1) i Co2 i 2 where, D 1 is he duy cycle of Q 1. From Eq. 1, i can be seen ha he sep-down oupu can be regulaed by D 1 and. B. Topology Exenion The proposed dual oupu converer can be exended o is n oupus version by adding n1 series-conneced swiches and LC ler neworks. The single inpu n oupus dc/dc archiecure can provide a high sep-up oupu and n-1 sep-down oupus. Fig. 6 demonsraes he schemaic of he exended circui.

The gae signal of Q n+1 is complemenary wih ha of Q n. Since G and G can be regulaed independenly, he sep-up and sep-down oupus can be conrolled independenly. I. ESULTS A 25 W, 42 inpu, 39, 15 oupus converer is designed. The specificaions and design parameers of he prooype are summarized in Table I.
