Ii-DC bus Capacitors zee-IGBT-Based Converters kwi-Traction Apparatus
Uthotho lwe-DMJ-MC yebhasi ye-DC
Ii-capacitor zefilimu ezenziwe ngesinyithi zenziwe ngeefilimu ezimbini ezenziwe ngesinyithi ezinefilimu yeplastiki njenge-dielectric.
Isinyithi se-aluminium esincinci kakhulu (~ 0.03 μm[2]) esifakwe kwi-vacuum sisetyenziswa kwicala elinye okanye omabini ukuze sisebenze njengee-electrodes.
