Phase Angle Firing Features

In each mains half-cycle the duration of thyristor or triac conduction is determined by the firing instant, relative to mains polarity changeover. Once switched on, the driven thyristors conduct power to the load until the end of each applied half-cycle, resulting in a chopped sine wave output. A ramp and pedestal input circuit, allowing variation of firing phase angle, enables more power through the load with increasing conduction angle. Step changes in load current generate Radio Frequency Interference (RFI). In sensitive applications this interference must be suppressed to comply with the relevant EMC standards or to prevent interaction with other components. This can be achieved by the addition of EMC mains filter networks.

Burst Firing Features

The number of complete mains cycles during fixed repeating periods (typically 1 to 10 seconds) is varied, thus altering the duty cycle or on-/off-time ratio. Trigger pulses coincide with the zero-crossing times of the mains supply thus ensuring no RFI is produced when using resistive loads.
