ZERO VOLTAGE SWITCH
The SL441C is a symmetrical burst control integrated
circuit in an 8 pin DIL package. When used with a triac, AC
power may be regulated by varying the number of mains
cycles applied to the load in a fixed timing period. The
device is especially suited to room temperature control
applications including panel heaters, fan heaters etc. Zero
Voltage Switching has the advantage of minimising radio
frequency interference.
FEATURES
I
Balanced zero voltage point crossing detector,
spike filter and pulse generator for reliable
triggering of the triac.
I
A period pulse generator and bistable which are
arranged to provide symmetrical burst control
and eliminate

wave firing. (EN50.006
BS5406,1976)
I
A ramp generator whose output is used to modify
an internal reference voltage which is then
compared with the voltage appearing on the
thermistor to form a proportional control system.
The period of the ramp generator is defined
externally and may be chosen to limit 'lamp flicker'
in accordance with EN50.006/BS5406, 1976.
I
The comparison amplifier has inbuilt hysteresis
to eliminate switching jitter and a spike filter/
sampling circuit to provide high immunity to both
spikes and coherent 50Hz/60Hz.
I
Thermistor malfunction may be sensed and power
automatically removed.
I
A supply voltage sensing circuit which inhibits
firing pulses when the supply is inadequate to
guarantee proper circuit operation. This eliminates
stressing of the triac at switch-on.
