Two-Pulse Phase-Angle Trigger Generator

Application

A 60 Hz synchronization source and 90 degree control voltage produce alternating trigger pulses on T1 and T2.

Schematic Organization

Synchronization and angle-control sources are on the left. The controller is centered. Separate trigger loads and probes are on the right.

Expected Behavior

T1 pulses during the positive half-cycle and T2 pulses during the negative half-cycle, each delayed by 90 electrical degrees.

Suggested Experiments

Change VALPHA from 90 V to 0 V or 180 V to move the firing pulses within each half-cycle.

Featured Component

Phase Angle Controller (2-Pulse) is the featured device. Its editor-visible symbol, pins, parameters, and simulation model are used directly in this circuit.
