Cel ćwiczenia.
Celem ćwiczenia jest zbadanie własności sterownika jednofazowego.
Układ pomiarowy.
Przebiegi prądu i napięcia obserwowane na oscyloskopie.
Przebiegi napięcia i prądu występujące na żarówce oraz triaku wykonane są na papierze milimetrowym.
Zmierzone napięcia skuteczne dla odpowiednich kątów wynośiły:
α=20° U=224V
α=60° U=201V
α=90° U=188V
α=165° U=38V
α=180° U=0V
Wyznaczone wartości graniczne kątów zapłonu triaka wynosiły:
αmin=20°
αmax=165°
4. Wyznaczanie charakterystyki sterowania.
