Parallel-Series Inverters,applied after allowing a certain time for the excess carriers in the outer and inner layers of the SCR to decay. The decay and recombination of these excess carriers may be accelerated by applying a reverse voltage across the SCR.

Choppers,ed voltage is removed for a duration known as . (.). The load power can be controlled by varying the on- and off-time. The ratio . to (. + .) is known as the .. This method can be applied to both AC and DC circuits. In AC circuits with direct on-off control, the load current is alternating, and therefore a triac can be very conveniently used.

Multiple Connections of SCRs, the required voltage and current ratings are lower than these maximum limits. Therefore, even though it may be possible to obtain a single SCR of proper voltage and current ratings, on many occasions the designer is forced to use lower-rated SCRs for reasons of economy and availability. In such a s
