Conclusion
AN441
AC switches are widely used to drive inductive loads. With inductive loads, triggering
synchronization with line voltage has a high impact on the inrush peak current and needs to
be controlled to minimize the first peak current and reduce the maximum junction
temperature.
Peak-voltage triggering or soft start solution allows inrush current reduction and the
maximum junction temperature to be considerably reduced.
