The ac/ac shopper fed from a single:phase V(t)=250 v2 sin(62.832t) V AC Source is compressed with on-off controland the 28 ohm heater resistance is bent. Effective surrentpassing through the resistor was measured as 6A if the thyristors remained in transmission and cut for 25 seconds for a period of time. Thuristors are ideal. According to this a) - Source frequency- - Qutout voltage, of AC chORre . V -Hz and period. m5n - The number of periods in which thyristor remain in the cut. - The number of periods in which thxristor remain transmission.- - The length of time the thuristor remain in transmission. b) Jf the same ac choper is phase:controlled and feeds an inductive load, the trigger angle of the thuristors is al=a2=60 and the silence angle is b=195 degrees. The forward voltage of a thyrcistor is 2v. The ammeter connected in series to a trisator in the circuit is (??okunmuyor??) A, and the value read in AC is 15.8 A. In this sase: -Ems value of the choRrer's output voltage,. v -average value of choRRer output voltage. -cms value of chopper outrut succent. V

V2
The ac/ac chopper fed from a single-phase V(t)=250 v2 sin(62.832t) V AC source is compressed with on-off controland the 28 ghm beater resistance is bent. Effective current passing through the resistor was measured as 6A if the thyristors remained in transmission and cut for 25 seconds for a period of time. Thwristors are ideal. According to this: a) - Source frequencY . Hz and period.. msn - Qutput voltage, of AC chorper . - The number of periods in which thyristor remain in the cut. - The number of periods in which thyristor remain transmission. V - The length of time the thyristor remain in transmission. b) If the same ac chopRer is phase-controlled and feeds an inductive load, the trigger angle of the thyristors is al=a2=60 and the silence angle is b=195 degrees. The forward voltage of a thyristor is 2V. The ammeter connected in series to a trisator, in the circuitis (??okunmuyor??) A, and the value read in AC is 15.8 A. In this case: -cms value of the chORper's output voltage.. V -average value of chopper output voltage. V -rms value of chopper output current . V
