NTROUTON NE EERAL YEAR, there is growing demnd for high voltge conversion systems cpble of providing high output voltge signls nd hving good spectrl performnce nd esy control. Exmples of such s systems re FAT devices, H light trnsmission, A drives, nd ctive filters [1, 2]. n ll the wellknown multilevel inverter topologies, the number of power devices required depends on the output voltge level needed. However, incresing the number of power semiconductor switches lso increse inverter circuit, control complexity nd cost. To provide lrge number of output levels without incresing the number of inverters, symmetric multilevel inverters cn be used [2]. The bsic elements used in symmetric multilevel inverter re GBTs nd diodes. Becuse of economicl nd technicl importnce of power dissiption, the designers must consider nd minimize the losses of these devices. The losses of switching device cn be clssified in three groups: offstte, conduction, nd switching losses. The lekge current during the offstte is negligibly smll therefore the power losses during this stte cn be neglected. As result, only conduction nd switching losses must be exctly modeled [1, 3, 4, 5]. There re severl methods to model these losses. n the cse of modeling with Pspice nd ber, the inverter circuits cn be schemticlly expressed by using ctul power semiconductor device models nd pssive elements [1, 6]. These models hve shown number of problems, such s complexity, slow execution times, lrge mount of generted dt, nd convergence [1, 6]. To overcome the mentioned limittions, switching function concept hs been developed [6]. n this pper, for threephse symmetric multilevel cscded inverter system the modeling methods of conduction nd switching losses bsed on switching function concept re presented.. AYMMETRAL MULTLEEL NERTER Asymmetric multilevel inverters hve exctly the sme circuit topology s symmetric multilevel inverters. They differ only in the used cpcitor voltges. The properties of symmetric multilevel inverters re however quite different from those of their symmetric versions. Especilly the number of outputvoltge levels cn be drmticlly incresed [2]. Figure 1 shows phse circuit digrm of n symmetric ninelevel cscded inverter. A number of modultion strtegies re used in multilevel power conversion pplictions. They cn generlly be clssified into three ctegorize: Multistep, pce ector PWM (PWM), nd rrierbsed PWM (BPWM) [1]. This pper focuses on crrierbsed PWM (BPWM) techniques which hve been extended for use in multilevel topologies by using multiple crriers. M. G. Hosseini Aghdm, nd. H. Fthi re with the eprtment of Electricl Engineering, Amirkbir University of Technology (Tehrn Polytechnic), No 424, Hfez Ave., Tehrn, rn (emil: Fig. 1.

Then using the eqution of (3), the switch currents re divided into the pure switch currents ( 1, b2, c1, d2 ) nd the pure diode currents ( 1, b2, c1, d2 ) s shown in figures 10 nd 11 for switches of b2, nd d2. Figures present the symmetric ninelevel cscded inverter losses bsed on equtions (4)(8). Figures (12) nd (14) (), (b) show the GBT nd diode conduction losses, respectively. Figures (13) nd (15) (), (b), (c) show the GBT turnon switching losses, GBT turnoff switching losses, nd diode turnoff switching losses, respectively. The suggested model for conduction nd switching losses is very ccurte. Therefore, in order to select the proper power semiconductor devices for symmetric multilevel inverter, the suggested model is very relible nd sfe. Also, the simultion runtime mesured of the suggested model is 100 times fster thn the ordinry method or Pspice simultion model. Also, this developed model solves the problems such s convergence nd complexity of circuit nd control.. ONLUON Bsed on switching function concept, the losses of threephse symmetric ninelevel cscded inverter hve been modeled with the using of MATLAB imulink. The suggested model is bsed on GBT nd diode chrcteristics modeling. Therefore, the clcultion of conduction nd switching losses by using this model is very ccurte. Also, n order to select the proper power semiconductor devices for symmetric multilevel inverter, the suggested model is very relible nd sfe. Also, this model is simple nd hs short runtime of simultion, too. Fig. 7. () GBT turnon/turnoff energy. (b) iode turnoff energy. (b).
