11.7 The single-phase full-wave ac voltage controller in Figure 11.2a has a resistive load of
R=5\Omega
and the input voltage is
V_(s)=150V(rms),60Hz
. The delay angles of thyristors
T_(1)
and
T_(2)
are equal:
\alpha _(1)=\alpha _(2)=\alpha =(\pi )/(3)
. Determine (a) the rms output voltage
V_(o)
, (b) the input PF, (c) the average current of thyristors
I_(A)
, and (d) the rms current of thyristors
I_(R)
. Could you solve only 11.7
