A matatu-phase thyristor rectifier Bridge inodiwa kudzora mota yeDC.Chishandiso chakakodzera chakakosha kuve nechokwadi chekushanda kwakagadzikana kweiyo yakapfava inotangisa kudzora mota uye inofanirwa kusarudzwa kuti ienderane nemidziyo yemota uye chinodiwa chehurongwa.Nheyo yekusarudza yakapihwa senge pazasi:

1.Condition: yekupinda voltage V_line=380V (3N 50Hz), yakabuda DC ikozvino I_d=3600A, kutonhora modhi ye thyristor kutonhora kwemhepo, tembiricha yenzvimbo T_A=40 ℃, iyo yaunoda kuvhiya ikozvino I_TSM=20KA.

2.Kusarudzwa kwemagetsi: kukosha kwepamusoro kweyero yakatemerwa line voltage

V_D(max)=*V_I=* 380 = 537V, iyo anti-impact coefficient inoonekwa se 2.5, fomula yekuverenga giredhi remagetsi ndeiyi: V._DSM≥537V*2.5= 1343V, saka

V_DSM= V_RSM= 1400V.

3.Kusarudzwa kwezvino: nekuda kwechidimbu che thyristor yakasiyana nekuwedzera kune yakasiyana-siyana ikozvino, saka tinofanira kuverenga kukosha kwakakodzera ikozvino kubva kune thyristor neVrrm = 1400V.I_d=3600A, avhareji yazvino inopfuura pane yega yega thyristor I_T=1200A, yakayerwa ikozvino ye thyristor I_T(AV)=1200A*2.5=3000A.

4.Sezvo mhepo inotonhorera heatsink ichasarudzwa maererano nehurukuro ye thyristor.

5.The thyristor uye heatsink inofanira kusarudzwa inopesana nekushandiswa uye zvakadzama zvinodiwa zvemotor control system.Iyo chikamu chekudzora thyristor uye heatsink inogadzirwa naJiangsu Yangjie Runau Semiconductor Co yakabatanidzwa zvakanyanya neiyo mamiriro ehunyanzvi tekinoroji yekugadzira yakakwirira simba semiconductor mudziyo.Inoshandiswa zvakanyanya mumotor transmission control application.Ndapota taura nenyanzvi dzedu nyanzvi kuti usarudze zvakakodzerathyristoruyeheatsinkkuitira kuita kwakanakisa kwekushandisa kwako.
