Extract

Līdzsprieguma avotam ar spriegumu U1=(150+0+1=151)V pieslēgts tranzistoru impulsregulators un slodze ar
R=(5+0+1=6) Ω. Impulsregulatora darba frekvence f=500Hz, relatīvais ieslēgšanas laiks D mainās no 0 līdz 1.
Noteikt nepieciešamo slodzes induktivitāti, lai slodzes strāvas pilnas pulsāvijas nepārsniegtu 10% no slodzes vidējās
strāvas. Aprēķināt ieejas filtra kondensatora kapacitāti un filtra droseles induktivitāti, lai kondensatora sprieguma un
droseles strāvas pilnas pulsācijas nepārsniegtu 10% no to vidējām vērtībām. Uzzīmēt shēmu! Parbaudīt ar
Virtuallab1 (DC step-down (buck) converter)!
Dots:
U1 = 151V
R = 6 Ω
f = 500Hz
