voltage.
f
switching frequency. The maximum L
must be calculated at low line and
high line.
The maximum on time occurs at the
lowest line voltage and maximum
output power.
The off time is greatest at the peak of
the AC line voltage and approaches
zero at the AC line zero crossings.
Theta (q) represents the angle of the
AC line voltage.

The turns ratio must be low enough
so as to trigger the ZCD comparators
at high line.
