3-phase, autonomous, voltage inverter controlled by MC 33035 in CD- reading application

Ovim radom je obrađeno napajanje CD čitača pomoću elektroenergetskih pretvarača. U tu svrhu je dan matematski model istosmjernog motora bez četkica, kao i njegova svojstva pri upotrebi. Zatim su navedeni kriteriji podjele izmjenjivača. Trofazni, autonomni, naponski izmjenjivač opterećen BLDC motorom je detaljno analiziran te su dobiveni izrazi i valni oblici koji ga opisuju. U konačnici su obrađeni integrirani krugovi MC33035, MC33039 i MPM3003 te je dana shema, kao i dizajn tiskane pločice za izradu izmjenjivača. Izrađeni izmjenjivač je testiran te su protumačeni rezultati mjerenjaThis paper deals with power converters used in CD-reading application. For that purpose, a brushless DC motor model was given with the motor characteristics. After that criterions for power inverter classification were given. 3-phase, autonomous, voltage inverters loaded with BLDC motors were analyzed in detail, and characteristic equations and wave forms were given. In the end, MC33035, MC33039 and MPM3003 were analyzed. Additionally, a schematics for a inverter with the earlier mentioned elements was given together with a PCB design. The manufactured inverter was tested and the measuring results were analyze
