An energy saving driving circuit and method is provided for use with a
solid state relay (SSR). The circuit and method reduce the overall energy
required to drive a solid state relay by maintaining the SSR in an "on"
state with a minimal maintenance or holding current after applying a
turn-n current. The driving circuit includes a control circuit configured
for outputting a control signal; a turn-on circuit configured for
providing an output current at a first current level for a first time
period in response to the control signal; and a holding circuit
configured for maintaining said output current at a second reduced
current level for a second time period. The maintenance or holding
current is reduced in respect of that of a conventional driving current,
and in some cases may be an order of magnitude or more less in magnitude
than a conventional driving currents thereby resulting in less energy
consumed by the SSR.
