The same task can be accomplished by a microprocessor which is synchronized to the AC zero crossing. The phase controlled trigger current may be a very short pulse which saves energy delivered to the input LED. LED trigger pulse currents shorter than 100s must have an increased amplitude as shown on Figure 4. This graph shows the dependency of the trigger current IFT versus the pulse width can be seen on the chart delay t(d) versus the LED trigger current. Figure 3 shows the increase of the trigger current when the device is expected to operate at an ambient temperature below 25C. Multiply the normalized IFT shown this graph with the data sheet guaranteed IFT.

The normalized IFT has to be multiplied with the devices guaranteed static trigger current. Phase Control Considerations LED Trigger Current versus PW (normalized) Random Phase Triac drivers are designed to be phase controllable. They may be triggered at any phase angle within the AC sine wave.

Inductive loads generate a commutating dv/dt that may activate the triac drivers noise suppression circuits. This prevents the device from turning on at its specified trigger current. It will in this case go into the mode of "half waving" of the load. Half waving of the load may destroy the power triac and the load. In Phase control applications one intends to be able to control each AC sine half wave from 0 to 180. Turn on at 0 means full power and turn on at 180 means zero power. This is not quite possible in reality because triac driver and triac have a fixed turn on time when activated at zero degrees. At a phase control angle close to 180 the driver's turn on pulse at the trailing edge of the AC sine wave must be limited to end 200ms before AC zero cross as shown in Figure 5. This assures that the triac driver has time to switch off. Shorter times may cause loss of control at the following half cycle. Figure 8 shows the dependency of the triac drivers IFT versus the reapplied voltage rise with a Vp of 400V. This dv/dt condition simulates a worst case commutating dv/dt amplitude. It can be seen that the IFT does not change until a commutating dv/dt reaches 1000V/ms. The data sheet specified IFT is therefore applicable for all practical inductive loads and load factors. IFT versus dv/dt Triac drivers with good noise immunity (dv/dt static) have internal noise rejection circuits which prevent false Figure. 7 Leakage Current, I DRM vs. Temperature 1000 IDRM - LEAKAGE CURRENT (nA) AC Sine 0 180 LED PW LED Current LED turn off min. 200s 100 10 1 Figure 5.

The mercury wetted relay provides a high speed repeated pulse to the D.U.T. The triac driver's turn on switching speed consists of a turn on delay time t(d) and a fall time t(f). Figure 9 shows that the delay time depends on the LED trigger current, while the actual trigger transition time t(f) stays constant with about one micro second. 2. 100x scope probes are used, to allow high speeds and voltages. 3. The worst-case condition for static dv/dt is established by triggering the D.U.T. with a normal LED input current, then removing the current. The variable RTEST allows the dv/dt to be gradually increased until the D.U.T. continues to trigger in response to the applied voltage pulse, even after the LED current has been removed. The dv/dt is then decreased until the D.U.T. stops triggering. RC is measured at this point and recorded. The delay time is important in very short pulsed operation because it demands a higher trigger current at very short trigger pulses. This dependency is shown in the graph IFT vs. LED PW. The turn on transition time t(f) combined with the power triac's turn on time is important to the power dissipation of this device.

For these applications a snubber circuit is not necessary when a noise insensitive power triac is used. Figure 11 shows the circuit diagram. The triac driver is directly connected to the triac main terminal 2 and a series Resistor R which limits the current to the triac driver. Current limiting resistor R must have a minimum value which restricts the current into the driver to maximum 1A. When the transient rate of rise and amplitude are expected to exceed the power triacs and triac drivers maximum ratings a snubber circuit as shown in Figure 12 is recommended. Fast transients are slowed by the R-C snubber and excessive amplitudes are clipped by the Metal Oxide Varistor MOV. Triac Driver Circuit for Extremely Noisy Environments As specified in the noise IEC255-4. Industrial control applications do specify a maximum transient noise dv/dt and peak voltage which is superimposed onto the AC line voltage. In order to pass this environment noise test a modified snubber network as shown in Figure 13 is recommended. R = Vp AC/ITM max rep. = Vp AC/1A The power dissipation of this current limiting resistor and the triac driver is very small because the power triac carries the load current as soon as the current through driver and current limiting resistor reaches the trigger current of the power triac. The switching transition times for the driver is only one micro second and for power triacs typical four micro seconds.
