AC Single Phase SSR Solid State Relay AC SSR of Single Dual In line
Description of AC Single Phase SSR Solid State Relay
Synchronous & random switching solid state relays
When switching high currents and using semiconductor devices that
can turn from off to on very quickly gives rise to sharp edges on
waveforms. In turn this can lead to high levels of electromagnetic
interference, EMI. As all devices these days must be designed to
minimise this interference, it is necessary to utilise ways that
minimise the generation of this EMI, so that the electromagnetic
compatibility, EMC performance of the device falls within the
required limits.
One method that can be used with AC and resistive loads, is known
as synchronous or zero crossing switching. As the name indicates
the solid state relay only turns on or off at the zero crossing
point of the AC waveform irrespective of the input control signal
timing.
Typical solid state relay
Whilst zero crossing SSRs are ideal for resistive loads, they do
not work properly with inductive loads because the current and
voltage are out of phase. Often they do not turn off properly.
For inductive loads, like transformers and motors, it is normal to
use random switching solid state relays. These devices turn on or
off at the instant required by the input control signal and they do
not take account of the position on the waveform.
